JavaScript (JS) is a lightweight, interpreted or just-in-time compiled high-level programming language with function precedence. Although best known as a scripting language for developing Web pages, JavaScript is also used in many non-browser environments. JavaScript is based on prototype programming, a multi-paradigm dynamic scripting language, and supports object-oriented, imperative, and declarative (e.g., functional) styles.

What does JavaScript mean?

JavaScript was first designed and implemented in Netscape Navigator in 1995 by Brendan Eich of Netscape. Because Netscape worked with Sun, Netscape management wanted it to look like Java, hence the name JavaScript. In fact, it is similar to Self and Scheme.

JavaScript is ECMAScript. As of 2012, all browsers fully support ECMAScript 5.1, with older versions supporting at least ECMAScript3. On June 17, 2015, ECMA International released the sixth edition of ECMAScript, officially known as ECMAScript2015, but commonly referred to as ECMAScript6 or ES6.

What does javascript mean by basic characteristics?

JavaScript is a high-level scripting language belonging to the network, which has been widely used in Web application development. It is often used to add various dynamic functions to web pages to provide users with more smooth and beautiful browsing effects. JavaScript scripts are usually embedded in HTML to achieve their own functionality.

Is an interpreted scripting language (code is not precompiled).

Mainly used to add interactive behavior to HTML (an application under the Standard Universal Markup Language) pages.

HTML pages can be embedded directly, but writing a separate js file facilitates the separation of structure and behavior.

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

Javascript scripting language, like other languages, has its own basic data types, expressions and arithmetic operators, and basic program framework for programs. Javascript provides four basic data types and two special data types for processing data and text. While variables provide places to store information, expressions can perform more complex information processing.

Human-computer interaction of web pages can be realized.
