https://tc39.es/ecma262/#sec-additional-syntax-string-literals The syntax and semantics of 11.8.4 is extended as follows except that this extension is not allowed for strict mode code: Syntax EscapeSequence:: CharacterEscapeSequence LegacyOctalEscapeSequence NonOctalDecimalEscapeSequence HexEscapeSequence UnicodeEscapeSequence LegacyOctalEscapeSequence:: OctalDigit [lookahead ∉ OctalDigit] ZeroToThree OctalDigit [lookahead ∉ OctalDigit] FourToSeven OctalDigit ZeroToThree OctalDigit OctalDigit ZeroToThree :: one of 0 1 2 3 FourToSeven :: one of 4 5 6 7 NonOctalDecimalEscapeSequence :: one of 8 9 This definition of EscapeSequence is not used in strict mode or when parsing TemplateCharacter. Note 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: function invalid() { "\7"; "use strict"; } |
