I get this questions from people why they have to use JavaScript on there web pages and they ask further is HTML and CSS not enough.

First, JavaScript is the programming language of the internet. You see JavaScript (Js for short) all over the internet. There are three languages every web programmer should know – HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript.

HTML tells a browser what content to show on your web pages. CSS tells the browser how to lay the content out and format it to look great. JavaScript controls the behavior of the page. All the popups, cool transitions, scrolling animations, and other attractive aspects of modern websites are created using JavaScript.

JavaScript improve your web pages by:

  1. It’s one of the few languages that isn’t run on the server that hosts the web page. If you’re a web developer, the time taken to load a page on a viewer’s browser must be as low as possible. The higher the load time, the lower the user experience. JavaScript animations use the viewer’s device processor to run themselves. This reduces the strain on the web server by a huge amount and cuts the page load time.


The syntax JavaScript uses is very similar to English. Developers don’t have to spend weeks figuring out what each snippet of code does when building a new site. When a developer uses JavaScript, your site will be open to the public that much faster.

3. Compatible with other languages.

Web servers use different languages to run well. Python, PHP, Ruby, Rails, ASP.NET, and Java are a few examples. Regardless of the language used on the server, your viewers will always have a rich, responsive experience because JavaScript works well with all of these languages.

4. Uses the DOM model

The DOM model is method of structuring a web page so that the elements are styled as “objects” with their own properties. This allows JavaScript to easily relate to all the elements and use them for animations or transitions with minimal issues. The DOM (Document Object Model) isn’t a programming language; it’s universal. A developer can write a DOM for a web page using JavaScript.

5. Compiler-free programming:

Traditional coding uses a compiler. A browser uses a compiler to translate raw code into readable syntax. This takes time and increases the load time of the page. It also increases the amount of time your site will be in development. On the other hand, browsers can natively read JavaScript. They can translate it the same way they do HTML. A compiler isn’t needed to make it readable.

6. Yes you absolutely need JavaScript.
