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, or it could also
add an escape sequence and return /\//g.
