What falls under the scope of ECMAScript?

The JavaScript programming language is standardized by ECMA (a standards body like the website) under the name ECMAScript. Among other things, ECMAScript defines:

• Language syntax–parsing Rules, keywords, statements, declarations, operators, etc.
• Types–boolean, number, String, object, etc.
• Prototypes and inheritance
• The standard library of built-in objects and functions– JSON , Math Array methods, Object introspection methods, etc.

What it doesn ' t define are anything to does with HTML or CSS, or the Web APIs, such as the DOM (Document Object Model). Those is defined in separate standards.  ECMAScript covers the aspects of JS that is present not only in the browser, but also in non-browser environments such as node. js.
