String Literals extensions disallowed in strict mode; ZeroToThree 3
|
|
info: |
|
|
It is possible for string literals to precede a Use Strict Directive that places the enclosing
|
|
code in strict mode, and implementations must take care to not use this extended definition of
|
|
EscapeSequence with such literals. For example, attempting to parse the following source text
|
|
must fail.
|
|
|
|
Strict mode is entered via the explicit Use Strict Directive.
