| 21.2.3.2.4 Runtime Semantics: EscapeRegExpPattern |
| |
| [...] The code points / or any LineTerminator occurring in the pattern |
| shall be escaped in S as necessary to ensure that the String value |
| formed by concatenating the Strings "/", S, "/", and F can be parsed |
| (in an appropriate lexical context) as a RegularExpressionLiteral that |
| behaves identically to the constructed regular expression. |
