Strict mode

Syntax

Remarks

Strict mode is an option added in ECMAScript 5 to enable a few backwards-incompatible enhancements. Behaviour changes in “strict mode” code include:

NOTE:- ‘strict’ mode is NOT enabled by default as if a page uses JavaScript which depends on features of non - strict mode, then that code will break. Thus, it has to be turned on by the programmer himself / herself.
