By | March 5, 2019

The world is now more focused on technology. Everything around us is surrounded by technology. But the thing to notice about it is how this technology is running? What’s that concept operating all technology?

That concept is the Programming Language which is behind every technology. Here we will discuss the programming languages with you and also we will introduce the Top 20 programming languages of 2019 or future.

Introduction to Programming Languages

What is Programming?

“A programming language is the way or set of rules used to send the instructions to the computer systems that what task they have to perform and how. It’s the way of communication with the computer system.”

In simple words, the programming language is the language of the computer. There are several programming languages available in the market and each programming language has its own set of grammatical rules which is known as syntax which must be followed.

Different programming languages are designed for different purposes. Every programming language comes with specific features.

Importance of Programming Languages

Importance of Programming Languages

In the current generation of technology, nothing is possible without a programming language. Here are the brief reasons why we learn and understand about a programming language:

  • Required to interact with machines and computers.
  • To automate tasks.
  • To harness the power of computing in all humans.
  • To create more intelligent technology and machines.

Top 20 Programming Languages of the Future

As the technology is growing and changing rapidly, new programming languages are also taking over the market and replacing the old ones. The competition is increasing on a high-speed day by day. To be in the race or programming, the developer just need to get updated with the latest trends in programming and the knowledge of top programming languages.

In this article, we have centralized our discussion on the top 20 programming languages of the future in 2019 and the brief introduction of the top languages.

So let’s start with this.

Python

Python Programming Languages

Python is the most popular language of 2018 and this will be on top in 2019 too. This was Language of the Year in 2018. Python is a high-level general purpose programming language supported by many useful libraries and provides web frameworks. Python is best for beginners to learn as its syntax is also very simple and almost like English.

Python is used for web development, desktop applications, web applications etc. Python web frameworks are Django, Flask, TurboGears, Web2Py etc. Mozilla, Instagram, and Spotify are examples of Django.

Python has also packages like NumPy and SciPy which are used largely in scientific computing, engineering, and mathematics.

Example:

# To add two numbers
num1 = 1.5
num2 = 6.3
# Add two numbers
sum = float(num1) + float(num2)
# Display the sum
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))
Output:
The sum of 1.5 and 6.3 is 7.8

JavaScript

Javscript Programming

Next, JavaScript holds the second position in the list of top 20 programming languages. It is a very famous scripting language and it is almost impossible to say that there is a developer without using JavaScript in some way. JavaScript is now used for both back-end and front-end development after Node.JS.

JavaScript is essential with HTML and CSS for front-end development. The popular giants like Facebook, Gmail, Twitter and YouTube also rely on JavaScript to design interactive front-end for users. JavaScript’s popular frameworks are Angular, React, Vue etc. JavaScript has a flexible syntax and supported by all major browsers.

Example:

<html>
<head>
<title>Multiplication Table</title>
<script type="text/javascript">
var rows = prompt("Enter number of rows: ");
var cols = prompt("Enter number of columns: ");
if(rows == "" || rows == null)
rows = 10;
if(cols== "" || cols== null)
cols = 10;
createTable(rows, cols);
function createTable(rows, cols)
{
var j=1;
var output = "<table border='1' width='500' cellspacing='0'cellpadding='5'>";
for(i=1;i<=rows;i++)
{
output = output + "<tr>";
while(j<=cols)
{
output = output + "<td>" + i*j + "</td>";
j = j+1;
}
output = output + "</tr>";
j = 1;
}
output = output + "</table>";
document.write(output);
}
</script>
</head>
<body>
</body>
</html>
Output:
Enter number of rows: 2
Enter number of columns: 2
1 2
2 4

Java

Java Programming Languages

Java is an object-oriented programming language and the base in the world of programming language for more than 20 years. Java is the most secure and portable language which follows “write once, run anywhere” concept. JVM (Java Virtual Machine) makes it portable and platform-independent. There are many competitive languages came to the market now but Java has still a long run to go. Java has one of the largest developer community. The android operating system is also based on Java programming language and android apps are also developed using Java.

As an rough idea, 90% of Fortune 500 companies are using Java.

Example:

public class Prime {
public static void main(String[] args) {
int num = 29;
boolean flag = false;
for(int i = 2; i <= num/2; ++i)
{
// condition for nonprime number
if(num % i == 0)
{
flag = true;
break;
}
}
if (!flag)
System.out.println(num + " is a prime number.");
else
System.out.println(num + " is not a prime number.");
}
}
Output:
29 is a prime number.

C++

C++

C++ is the start of object-oriented programming which builds on C with the OOPs features. C++ is a flexible and highly efficient programming language. C++ is always strong and well-performed language. Google Chrome and Microsoft Windows are the best examples of this. If you are going to start a career in any object-oriented programming than it is must learn C++ for you. C++ is used to develop desktop applications, GUI applications, 3D games, and real-time mathematical solutions.

Example:

#include <iostream>
using namespace std;
int main()
{
cout << "Hello, World!";
return 0;
}
Output:
Hello, World!

PHP

PHP programming Languages

Yes, this is PHP still in the list. PHP is still in the list, so if you are thinking PHP is gone now then you are wrong. It is a Pre-processor Hypertext (PHP) server-side scripting language used for backend development. This is the technology behind Facebook, Yahoo, and Wikipedia also. PHP is also there in WordPress CMS (Content Management System), which makes it easiest to have a website for the masses.

PHP with JavaScript is a combination behind so many purposes like creating cookies, collecting and verifying form data, and to display dynamic content and images.

Most popular PHP frameworks are Laravel and Drupal which make PHP more robust, secure, and scalable.

Example:

<!DOCTYPE>
<html>
<body>
<?php
echo "<h2>Hello First PHP</h2>";
?>
</body>
</html>
Output:
Hello First PHP

Swift

Swift Programming Languages

For iOS and Android mobile app development, Swift is a highest-paid career path. Swift programming language was released in 2014. It’s a relatively new language and a good place to start. Swift is growing rapidly and according to Github’s report, Swift is the 13th most popular programming language. As the scope of iOS apps are increasing, the number of swift developers are also increasing.

Swift is easy to understand and very expressive language. Even beginners also can develop powerful and flexible apps with the Swift language. Apple’s iPhone always remains at its top position in best mobile smartphones so the career growth in choosing Swift for the future will also be on high.

Example:

class Counter {
var count = 0
func increment() {
count += 1
print("value of count in increment() func is ",count)
}
func increment(by amount: Int) {
count += amount
print("value of count in increment(by:) func is ",count)
}
func reset() {
count = 0
print("value of count in reset func is ",count)
}
}
let counter = Counter()
counter.increment()
counter.increment(by: 5)
counter.reset()
/* prints:
value of count in increment() func is 1
value of count in increment(by:) func is 6
value of count in reset func is 0
*/

C#

C# Programming Languages

Pronounced as C Sharp. It is an object-oriented general-purpose programming language which is built on the foundation of C. C++ is a part of .Net framework of Microsoft for building Windows applications. Just as Swift is for iOS applications C# is for Microsoft platforms. C# also has syntax like other C-derived languages like C++ so it is easy to adopt if you are familiar with the C family.

C# is also used to build cross-platform applications on the Xamarin Platform. By using C#, you can write lengthy codes in a single line with the Xamarin platform and then deploy to both platforms like iOS and Android simultaneously.

If you are crazy about VR and want to go with this then you have to choose C# to learn. The best thing about C# is it gives you the ability to develop any application you want, starting from the complex APIs to desktop applications.

Example:

namespace SumGenerator
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Write the first integer:");
int first = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Write the second integer:");
int second = Convert.ToInt32(Console.ReadLine());
int result = first + second;
Console.WriteLine($"The result is {result}");
Console.ReadKey();
}
}
}
Output:
Write the first integer:
5
Write the second integer:
15
The result is 20

Kotlin

Kotlin

It’s an open-source product by JetBrains. This is 2nd most loved and demanding programming language of 2018. A statically typed language runs on JVM and Kotlin can translate to JavaScript source code. Kotlin is another option to whom those don’t want to make Android apps with Java and Google officially recommends it now. Kotlin is compatible with Android Studio 3 and this is the reason behind its popular growth.

Soon, Kotlin will be in most used languages as it is already used by popular productions like Netflix, Pinterest, Amazon web services etc. If things will go at the same speed, soon Kotlin will be the new replacement of Java.

Example:

fun main(args: Array<String>) {
val first: Int = 10
val second: Int = 20
val sum = first + second
println("The sum is: $sum")
}
Output:
The sum is: 30

Go Programming Language

Go Programming Languages

Go is simple to write like Python but more efficient like C++. The mastermind behind this subtle approach are Robert Griesemer, Ken Thompson, and Rob Pike and developed by Google. Go has the ability to handle the hardest computational problems. Go is the advanced added featured version of C including compiled language, statically typed, garbage collection, structural typing, and CSP-style concurrency. Kubernetes and Ethereum Cryptozoic Project rebased on Go. Go is the new programming language with helpful new community and very compelling for your next open source project.

Example:

package main
import "fmt"
func main() {
var greeting = "Hello world!"
fmt.Printf("String Length is: ")
fmt.Println(len(greeting))
}
Output:
String Length is: 12

SQL

SQL Programming

From the decades, SQL is still on the top of its position and most important for breaking the interviews. SQL is primarily used for solving the problems of data management and cant used for developing traditional software, but still, it is able to handle data associated with modern applications.

With the growth in data analytics field, SQL also opens up possibilities for developing advanced open-source projects. As we noticed that a large number of data based projects are coming out rapidly, it’s time to embrace SQL as the most powerful programming languages and build extraordinary.

Example:

Selecting Distinct values from the table?

Query:

Select Distinct Name From Employee;

Ruby

Ruby Programming

Ruby is the most used programming language and its not a new language. Ruby was developed in the mid-90s and gained high popularity also. Ruby is an object-oriented programming language including features like dynamic and interpreted. It is much like Python and has similarity in many aspects. Ruby is basically used as popular Ruby on Rails web application framework. Ruby provides friendliest and most helpful user communities. Ruby’s chief inventor is Yukihiro Matsumoto. He always encourages members, therefore, the community also has the tagline “Matz is nice and so we are nice.”

Most of the modern web apps such as Airbnb, Github, ASKfm, Fiverr, and Goodreads are utilizing Ruby in one way or another.

Example:

puts "puts works"
puts " with line breaks."
print "print works"
print " with no line breaks."
printf("\n\nprintf formats numbers like %7.2f, and
strings like %s.",3.14156,"me")
Output:
puts works
with line breaks.
print works with no line breaks.
printf formats numbers like 3.14, and strings like
me.

Perl

Perl programming

The main purpose behind the development of the Perl language is the manipulation of text documents. Also, it is used in the implementation of web devilment, network programming, system administration etc. Perl is also a popular and one of the most used programming languages. Perl has gained popularity as well as faced criticism at the same time. But still, it is used in many large organizations.

Companies that used large codebases of legacy programs often search for Perl developers to retain and upgrade their old used systems. Choosing Perl can boost your open source credibility.

Example:

#!/usr/bin/perl
print "Hello, world!";
Output:
Hello, world!

R Programming Language

R Programming Language

R is one of the most popular programming languages used for complex statistical analysis and graphics programming. Mainly it is used for ad hoc analysis and to explore large datasets.

R is the second most used programming language for data science after Python. It is often used for data mining projects also. R language is much stronger than other statistical programming languages when compared with respect to object-oriented features. You can use Rd for professional documentation for your open-source projects which are R’s own LaTeX-like documentation. So use the R programming language for accurate, clean, and efficient data visualization in your open-source project.

Example:
Output: “How are you?”

TypeScript

Typescript

TypeScript is a trendy programming language by Microsoft. TypeScript is designed as the subset of JavaScript with the with the advanced ability of static typing. TypeScript can be used for all type of web application even for large-scale application with desktop applications, front-end, and back-end development, architect cloud solutions, hybrid mobile applications, design neural networks, to control robots, and these all are possible by using the cross-platform framework like Electron.

The good news about TypeScript is Google decided to use it in Angular. If you are looking to build next-generation web applications using the modern approach, you can go with the TypeScript for your next open-source project.

Example:

var message:string = "Hello World"
console.log(message)

Output:
On compiling, it will generate the following JavaScript code.

//Generated by typescript 1.8.10
var message = "Hello World";
console.log(message);

Rust

Rust

The most loved and wanted programming language by the stack overflow developer survey for three consecutive years now and 78.9% of Rust developers want to continue working with it. Rust is a system-level programming language which is changing the way of programming. Rust is developed by Mozilla Foundation and it is more like C and C++ and emphasized on speed and security.

For beginners, it may be tough initially as it is strict about some rules to provide memory safety. However, with the practice, one can become familiar with it very soon. Big companies like Dropbox and Coursera started using it internally. Rust will definitely be in demand in near future. If you are looking for a powerful and futuristic programming language then Rust is a good logical option.

Example:

fn main() {
println!("Hello World");
}
Output:
Hello World
/pre<>

Scheme

Scheme

The scheme is one of Lisp’s two main languages. It is a multi-purpose programming language that aims at extending the core with powerful language extensions. It is used for system applications development with its minimalistic approach. Scheme was originated at the infamous MIT AI Lab. It is a very old language and used widely by big giants like Google and Reddit. To choose a very old and secure language in the era of Perl and Lisp, you will definitely love Scheme at first glance. Example:

(display "Hello, World!")
Output:
Hello, World!

Scala

Scala Programming Language

Scala is a modern programming language with the combined approach of functional programming with object-oriented programming. It’s designed with an innovative approach aimed to address criticism of Java.

A statically typed language which aimed to fix bugs right from the development period. Scala is able to run on both Java Virtual Machine (JVM) and JavaScript Runtime and this is the key factor behind its rapid popularity. You can use Scala for the complex web applications that require both low and upscaling.

Example:

object HelloWorld {
def main(args: Array[String]) {
println("Hello, world!")
}
}
Output:
Hello, world!

Erlang

Erlang

This is a general-purpose language with the built-in runtime environment. Erlang is gaining momentum in the latest programming languages. It includes the smart implementation features like distributed, hot-swapping components, and fault-tolerant etc. Developers will be able to use an immutable data structure with Erlang as well as functional programming with the pattern matching support.

This is the best new programming language which is suitable for solving complex problems. The language can solve real-world problems and able to interact via passing messages.

Example:

% hello world program
-module(helloworld).
-export([start/0]).
start() ->
io:fwrite("Hello, world!\n").
Output:
Hello, world!

Haskell

Haskell

The another fastest growing latest programming language is Haskell programming. This is also statically typed language with the modern approach for new application development. The name is given after logician Haskell Curry. Haskell is a purely functional programming language with Type Classes, which enable type-safe operator overloading.

Haskell is based on Miranda which is the oldest computer programming language to take a lazy functional approach. The popular social media platform Facebook’s anti-spam mechanism is built through Haskell programming.
Example:

main = putStrLn "Hello World"
Output:
Hello World

Elixir

Elixir

Elixir is one of the top programming languages based on Erlang and uses Erlang Runtime Environment (BEAM) to run the code. This language supports advanced functionalities such as polymorphism, macros, and metaprogramming. Elixir is come out with high features and sky-high capabilities.

The language is slowly gaining the place in Top programming language from the new programming languages but it is already being used by big companies like Pinterest, E-MetroTel, Discord, Inverse, and Bleacher Report etc.

Example:

# Value of pi
IO.puts(:math.pi())
# Logarithm
IO.puts(:math.log(7.694785265142018e23))
# Exponentiation
IO.puts(:math.exp(55.0))
#...
Output:
$elixir main.exs
3.141592653589793
55.0
7.694785265142018e23
