Notes

As the specification includes many JavaScript features, un-numbered partial support varies widely and is shown in detail on the ECMAScript 5 compatibilty tables by Kangax.

  1. Does not support parseInt() ignoring leading zeros.

  2. Does not support Strict mode

  3. Does not support zero-width chars in identifiers & Immutable undefined

  4. IE8 has virtually no ES5 support, but does support Object.defineProperty, Object.getOwnPropertyDescriptor, JSON parsing & Property access on strings
