ECMAScript Reserved Words
ECMA-262 defines a set of ECMAScript supportedReserved Word (Reserved Word).
Reserved words are words reserved for future keywords in some sense. Therefore, reserved words cannot be used as variable names or function names.
The complete list of reserved words in ECMA-262 Third Edition is as follows:
abstract boolean byte char class const debugger double enum export extends final float goto implements import int interface long native package private protected public short static super synchronized throws transient volatile
Note:If a reserved word is used as a variable name or function name, it is likely that no error message will be received unless the reserved word is implemented by the browser in the future. When the browser implements it, the word will be treated as a keyword, and a keyword error will occur.
