24.160. RegExp.toString( ): convert a regular expression to a string

ECMAScript v3: Overrides Object.toString( )

24.160.1. Synopsis

regexp.toString( )

24.160.1.1. Returns

A string representation of regexp.

24.160.1.2. Throws

24.160.2. Description

The RegExp.toString( ) method returns a string representation of a regular expression in the form of a regular-expression literal.

Note that implementations are not required to add escape sequences to ensure that the returned string is a legal regular-expression literal. Consider the regular expression created by the expression new RegExp("/","g"). An implementation of RegExp.toString( ) could return ///g for this regular expression; it could also add an escape sequence and return /\//g.
