With the help of JS, you can turn a static page into an interactive page. It will allow you to add behavior to your webpage. You can consider it to be the third layer after HTML and CSS.
We will discuss how JS has evolved over the years. It was all started in 1993 with the introduction of the first commercial browser by Netscape Communications Corporation. It was designed to improve information sharing.
- In 1995, Brendan Eich developed the web scripting language.
- Netscape submitted JS to ECMA International in 1996, and the official release was made in 1997.
- In 1996, ECMAScript became the official name for the language.
- After 2015, the ECMAScript is named by year. For example, ECMAScript 2015.
- ES6 (ECMAScript 2015) comes with support for most browsers.
- ES7 (ECMAScript 2016) comes with Chrome and Opera support.
- From 2016 to 2019, a new version of ECMAScript was published every year.
- New updates are still going on.
- It allows you to extend the interactive features and interfaces to web applications, including animations, videos, audios, and other modern web experiences.
- It works faster as it is executed at the client’s device rather than the website’s server, and it will minimize the server requests.
- Today, almost all browsers come with JIT compilation for JS, which reduces the time for code compilation before executing it.
- It is easy to add JS code to the webpage. You can use JS for different applications as it shows support for languages like PHP and Perl.
- The code is easy to learn, handle, and debug due to its flexible syntax and can be used inside scripts of other languages.
No programming language is perfect, and JS is no exception. Below are some disadvantages of using the popular programming language:
- The code can be vulnerable to malicious code injection and cross-site scripting attacks. It allows hackers to alter the code of the web page to make them function differently. You may not always detect the attack.
- If the user has disabled the JS extension for the browser, then the code will not work.
- It does not work with old browsers.
Whenever you load a webpage in your browser, code will run in the execution environment. It takes the code as input and results in a webpage. Then JS will modify HTML and CSS code to enhance the user interface dynamically. The code should be executed in the same order in which it appears on the page; otherwise, the page will get impacted.
If you are learning any language, then it is a good practice to know about its tools, frameworks, IDEs, and existing libraries. Using all these, you can excel and can work on improving the webpage.
- Framework - It is a platform that offers a standard way to develop applications. JS has many popular frameworks, including Node, Electron, Angular, and BackBone.
- Tools - They provide assistance in order to make the application smooth and efficient. JSLint, Mocha, and Browserify are some of the popular JS tools.

To add interactive behavior to your webpage
Once you are into JS, there is no limit to what you can do with it. There are many features that you can add to your webpages to make them interactive for your customers and visitors. Here are some examples that you can consider:
- Changing button colors on hover,
- Zoom in and out with a click or mouse hover,
- Displaying animations,
- Using different menus,
- Including image carousel,
- Embedding audio and video within your webpage.
These are a few examples, but you can explore more options and features that will make the website more attractive.

To develop browser games
With the help of the popular programming language, you can even develop browser games. It has the EaselJS library that provides an easy solution to work with rich graphics to make your game more interactive. The library also has 2D bitmaps that allow rendering the target for transformation.
