This article will explain in detail what the main role of JavaScript is. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

What is the main function of JavaScript?

It has been mentioned above that JavaScript can achieve page effect switching, animation effects, page games and other effects. JavaScript, however, takes on more responsibility. Especially with the rise of Ajax technology, the user experience of the website has been greatly improved. For example, when people type a few words into Baidu's search box, the web page will intelligently perceive what the user is going to search next, and a drop-down menu appears, which can't be achieved without JavaScript. In addition, the use of JavaScript is no longer limited to browsers. The emergence of Node.js enables developers to write JavaScript code on the server side, which makes JavaScript more widely used.

Daily use of JavaScript

1. Embed dynamic text and HTML pages

2. Correspond to the browser time

3. Read and write HTML elements

4. Verify the data before it is submitted to the server

5. Detect the browser information of visitors

6. Control cookies, including creation and modification, etc.

7. Server-side programming based on node.js technology.
