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. */ #define JS_VERSION_ECMA_3 148 #define JS_VERSION_ECMA_3_TEST 149 #if JS_VERSION == JS_VERSION_ECMA_3 || \ JS_VERSION == JS_VERSION_ECMA_3_TEST #define JS_HAS_STR_HTML_HELPERS 0 /* has
