JavaScript (or ECMAScript) is a high-level, dynamic, untyped, and interpreted programming language.

JavaScript is a scripting language developed by Brendan Eich of Netscape and was called Mocha in 1995

JavaScript has been standardized in the ECMAScript language specification.

JavaScript, alongside HTML and CSS, is one of the three core technologies of World Wide Web content production; the majority of websites employ it, and all modern Web browsers support it without the need for plug-ins.

JavaScript is prototype-based with first-class functions, making it a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles.

JavaScript has an API for working with text, arrays, dates and regular expressions, but does not include any I/O, such as networking, storage, or graphics facilities, relying for these upon the host environment in which it is embedded.
