JavaScript Reference Manual

JavaScript complete reference manual downloadJavaScript is Microsoft's implementation of the ECMA 262 language specification (ECMAScript Editor 3). With few exceptions (to maintain backward compatibility), JavaScript fully implements the ECMA standard.
JavaScript is an interpreted, object-based scripting language. Although JavaScript is less powerful than a mature object-oriented language like C, it is powerful enough for its intended use.
JavaScript is not a stripped-down version of other languages ​​(it is only vaguely and indirectly related to Java, for example), nor is it a simplification of anything. However, it has its limitations. For example, you cannot use the language to write standalone applications, and there is no built-in support for reading and writing files. In addition, JavaScript scripts can only run on a certain interpreter or "host", such as Active Server Pages (ASP), Internet Browser, or Windows Script Host.
The remainder of this reference manual is an overview of JavaScript features.
