What is JavaScript

JavaScript is a dynamically typed, weakly typed, prototype-based language. Its interpreter is called the JavaScript engine, which is part of the browser and is widely used in client-side scripting languages. It was first used on HTML web pages to add dynamic functions to HTML web pages.

JavaScript is a network scripting language that has been widely used in Web application development. It is often used to add various dynamic functions to web pages to provide users with smoother and more beautiful browsing effects. Usually JavaScript scripts realize their functions by embedding them in HTML.

JavaScript is a cross-platform interpreted language that does not require pre-compilation and can run under various operating systems.

What JS can do

JavaScript can be used in various fields of web development, such as:

• Web application development: The web pages we browse in daily life are composed of HTML, CSS, and JavaScript. JavaScript can update the styles of elements in the web page in real time, and enable interaction between people and web pages (such as monitoring whether the user clicks the mouse or presses the button). Press a certain button, etc.), you can also add some cool animations to the web page; [Related recommendations: javascript learning tutorial]

• Mobile application development: In addition to web application development, JavaScript can also be used to develop applications on mobile phones or tablets, and we can also use some excellent frameworks (such as React Native) to make development easier;

• Web games: The small games we have played on the web can all be implemented using JavaScript;

• Back-end Web application development: In the past, we all used JavaScript To develop the front-end part of a Web application, but with the emergence of Node.JS (a JavaScript runtime environment), JavaScript can also be used to develop the back-end part of a Web application.
