Is JavaScript a markup language?

JavaScript is not a markup language.

JavaScript (JS) is a lightweight, interpreted or just-in-time programming language with function precedence. Although it is 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, declarative, and functional programming paradigms.

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 ECMAScript 3. On June 17, 2015, ECMA International released the sixth edition of ECMAScript, officially known as ECMAScript 2015, but commonly referred to as ECMAScript 6 or ES2015.

Introduction to markup languages:

A markup language is a computer word code that combines text and other information about text to reveal details about document structure and data processing. Other information about the text (including structure and presentation information) is combined with the original text, but identified using tags.

A markup language is more than just a language; like many languages, it requires a runtime environment in order to be useful. The elements that provide the runtime environment are called user agents.

Markup languages can generally be divided into three categories: symbolic, procedural, and descriptive.

Common:

Hypertext Markup Language

Hypertext Markup Language (HTML) is a markup language designed for web page creation and other information that can be viewed in web browsers.
