* Compile-time JS version configuration. The JS version numbers lie on the
|
|
* number line like so:
|
|
*
|
|
* 1.0 1.1 1.2 1.3 1.4 ECMAv3 1.5 1.6 1.7 1.8 ECMAv5
|
|
* ^ ^
|
|
* | |
|
|
* basis for ECMAv1 close to ECMAv2
|
|
*
|
|
* where ECMAv3 stands for ECMA-262 Edition 3, and ECMAv5 stands for Edition 5.
|
|
* See the runtime version enum JSVersion in jspubtd.h. Code in the engine can
|
|
* therefore count on version <= JSVERSION_1_4 to mean "before the Third
|
|
* Edition of ECMA-262" and version > JSVERSION_1_4 to mean "at or after the
|
|
* Third Edition".
|
|
*
|
|
* In the (likely?) event that SpiderMonkey grows to implement JavaScript 2.0,
|
|
* the version number to use would be near 200, or greater.
|
|
*
|
|
* The JS_VERSION_ECMA_3 version is the minimal configuration conforming to
|
|
* the ECMA-262 Edition 3 specification. Use it for minimal embeddings, where
|
|
* you're sure you don't need any of the extensions disabled in this version.
|
|
* In order to facilitate testing, JS_HAS_OBJ_PROTO_PROP is defined as part of
|
|
* the JS_VERSION_ECMA_3_TEST version.
|
|
*
|
|
* To keep things sane in the modern age, where we need exceptions in order to
|
|
* implement, e.g., iterators and generators, we are dropping support for all
|
|
* versions <= 1.4.
