48 * Compile-time JS version configuration. The JS version numbers lie on the
49 * number line like so:
51 * 1.0 1.1 1.2 1.3 1.4 ECMAv3 1.5 1.6 1.7 1.8 ECMAv5
54 * basis for ECMAv1 close to ECMAv2
56 * where ECMAv3 stands for ECMA-262 Edition 3, and ECMAv5 stands for Edition 5.
57 * See the runtime version enum JSVersion in jspubtd.h. Code in the engine can
58 * therefore count on version <= JSVERSION_1_4 to mean "before the Third
59 * Edition of ECMA-262" and version > JSVERSION_1_4 to mean "at or after the
62 * In the (likely?) event that SpiderMonkey grows to implement JavaScript 2.0,
63 * the version number to use would be near 200, or greater.
65 * The JS_VERSION_ECMA_3 version is the minimal configuration conforming to
66 * the ECMA-262 Edition 3 specification. Use it for minimal embeddings, where
67 * you're sure you don't need any of the extensions disabled in this version.
68 * In order to facilitate testing, JS_HAS_OBJ_PROTO_PROP is defined as part of
69 * the JS_VERSION_ECMA_3_TEST version.
71 * To keep things sane in the modern age, where we need exceptions in order to
72 * implement, e.g., iterators and generators, we are dropping support for all
