Description
jаvascript is an interpreted programming language, that is, it needs an interpreter in order to be executed.

jаvascript is mostly used within web pages but its use as a server or application begins to spread.

Like HTML, jаvascript is usually executed by the browser of the user: it is about a client-side behavior, as opposed to the server-side when the code is executed by the server.

jаvascript is standardized by ECMA International under the name of ECMAScript which constitutes the reference of the language.

The latest standardized version of jаvascript is based on ECMAScript 5, released in 2009. But its new version, ECMAScript 6, is gaining ground.
