disallowQuotedKeysInObjects

Disallows quoted keys in object if possible.

Types: Boolean, String or Object

Values:

• true for strict mode
• "allButReserved" (deprecated use "allExcept": ["reserved"])
• Object:
  • "allExcept" array of exceptions:
    • "reserved" allows ES3+ reserved words to remain quoted which is helpful when using this option with JSHint's es3 flag.

Valid for mode true

var x = { a: { default: 1 } };

Valid for mode {"allExcept": ["reserved"]}

var x = {a: 1, 'default': 2};

Invalid

var x = {'a': 1};
