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.

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 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.


# 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))
The sum of 1.5 and 6.3 is 7.8


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.

<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'>";
output = output + "<tr>";
output = output + "<td>" + i*j + "</td>";
j = j+1;
output = output + "</tr>";
j = 1;
output = output + "</table>";
Enter number of rows: 2
Enter number of columns: 2
1 2
2 4


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.


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;
if (!flag)
System.out.println(num + " is a prime number.");
System.out.println(num + " is not a prime number.");
29 is a prime number.



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.

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(by: 5)
/* 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# 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.

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}");
Write the first integer:
Write the second integer:
The result is 20



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.

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!")
Hello, World!


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.


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



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.
