What is JavaScript used for?

JavaScript is an object-oriented programming language used for multiple websites for scripting web pages. It’s a full-fledged and interpreted programming language. It can also enable dynamic interactivity on the websites when applied to the HTML document.

JavaScript can help all users to develop modern web apps to communicate directly by reloading the page. This is a commonly used programming language that will dynamically modify CSS and HTML. Doing so will help update the user interface through the DOM API. But before you use this, it is important to learn about it.

What exactly is JavaScript designed for?

JavaScript was developed by Brendan Eich at Netscape to eliminate the restriction of the static pages present on the web. He created a scripting language that utilized Java’s syntax, another programming language. Besides that, there are several other reasons why JavaScript was developed:

  1. Speed: It’s a lot quicker to execute code in a website browser in its native language instead of executing code on the server.
  2. Reduces the Memory Use: When the code gets executed in the browser, it frees up space on the server. In return, it helps in cutting down costs.
  3. Dynamic Pages: It was only possible for the users to interact with pages after the inception of JavaScript.
  4. Reloads Specific Parts of the Page Autonomously: All those suggestions you make when you begin typing in Google’s search section are all due to JavaScript.
  5. Responsive Content: When you change the window’s size of the browser, JavaScript makes the content’s size change with it.
  6. Developing Responsive User Interfaces: The majority of the user interfaces of the social media platform depend on JavaScript.
  7. Play Video and Audio: Do you remember Flash? JavaScript’s video and audio capabilities are why it’s obsolete. HTML got the chance to take care of all the media files. But JavaScript was the first to do it.
  8. Create a Validation: In JavaScript, all the needed fields are enforced. This way, you will get all the crucial information when shopping online.
  9. Autocomplete: This programming language will save you manually providing the email address to fill out an online form.
