What does js mean?

JavaScript was first designed and implemented in Netscape Navigator browser by BrendanEich of Netscape in 1995. Because Netscape works with Sun, Netscape management wants it to look like Java, so it is named JavaScript. But in fact, its grammar style is similar to that of Self and Scheme.

The standard of JavaScript is ECMAScript. As of 2012, all browsers fully support ECMAScript5.1, and older browsers support at least the ECMAScript3 standard.

It is often used to add a variety of dynamic functions to web pages and provide users with a more smooth and beautiful browsing effect.

Is an interpretive scripting language (the code is not precompiled).

Mainly used to add interactive behavior to HTML (an application under the standard general markup language) page.

You can embed a HTML page directly, but writing it as a separate js file facilitates the separation of structure and behavior.

Cross-platform feature, supported by most browsers, can run on a variety of platforms (such as Windows, Linux, Mac, Android, iOS, etc.).

Like other languages, Javascript scripting language has its own basic data types, expressions and arithmetic operators, and a basic programming framework for programs.
