ECMAScript - edition 2 (Standard)

Specific conformance for ECMAScript at its second edition.

The character encoding support described in the second edition of the standard is very specific:

"A conforming implementation of the International standard shall interpret characters in conformance with the Unicode Standard, Version 2.0, and ISO/IEC 10646-1 with UCS-2 as the adopted encoding form, implementation level 3. If the adopted ISO/IEC 10646-1 subset is not otherwise specified, it is presumed to be the BMP subset, collection 300."

Other than typographical and editorial changes, little was added between the first and second editions of the ECMA standard. That means this edition becomes the foundation specification for the core language.

The principle features of this edition include:
