/*
|
||
* If regexp is not an object of type RegExp, it is replaced with the
|
||
* result of the expression new RegExp(regexp). Let string denote the
|
||
* result of converting the this value to a string. String is searched
|
||
* for the first occurrence of the regular expression pattern regexp if
|
||
* regexp.global is false, or all occurrences if regexp.global is true.
|
||
*
|
||
* The match is performed as in String.prototype.match, including the
|
||
* update of regexp.lastIndex. Let m be the number of matched
|
||
* parenthesized subexpressions as specified in section 15.7.5.3.
|
||
*
|
||
* If replaceValue is a function, then for each matched substring, call
|
||
* the function with the following m + 3 arguments. Argument 1 is the
|
||
* substring that matched. The next m arguments are all of the matched
|
||
* subexpressions. Argument m + 2 is the length of the left context, and
|
||
* argument m + 3 is string.
|
||
*
|
||
* The result is a string value derived from the original input by
|
||
* replacing each matched substring with the corresponding return value
|
||
* of the function call, converted to a string if need be.
|
||
*
|
||
* Otherwise, let newstring denote the result of converting replaceValue
|
||
* to a string. The result is a string value derived from the original
|
||
* input string by replacing each matched substring with a string derived
|
||
* from newstring by replacing characters in newstring by replacement text
|
||
* as specified in the following table:
|
||
*
|
||
* $& The matched substring.
|
||
* $‘ The portion of string that precedes the matched substring.
|
||
* $’ The portion of string that follows the matched substring.
|
||
* $+ The substring matched by the last parenthesized subexpressions in
|
||
* the regular expression.
|
||
* $n The corresponding matched parenthesized subexpression n, where n
|
||
* is a single digit 0-9. If there are fewer than n subexpressions, “$n
|
||
* is left unchanged.
|
||
*
|
||
* Note that the replace function is intentionally generic; it does not
|
||
* require that its this value be a string object. Therefore, it can be
|
||
* transferred to other kinds of objects for use as a method.
