Documentation

FESI implements few language extensions and try to follow the standard as much as possible. This is unlike most implementation of JavaScript, which are unfortunately very incompatibles between them. For the core language definition you can refer to the `ECMA 262` standard. Admittedly this is not a tutorial.

Netscape provides a JavaScript user guide and reference guide. Unfortunately the Netscape specific extensions are not clearly distinguished from the EcmaScript core. Microsoft provides an introduction and reference to JScript, which separates the Microsoft extensions from the standard core.

I have not written any general description of EcmaScript, so you will have to make do with the above references. Note that most books on JavaScript describes more the JavaScript navigator extensions rather the language itself.

The following documentation is available:

Interpreter: | The easier way to get familiar with EcmaScript is to use the interpreter.
Java Library: | To embed EcmaScript in your application you will have to use the library.
Extensions: | Basic input/output, access to Java packages and more is reachable by loading extensions
