/* | |
* 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. | |
