18 * If regexp is not an object of type RegExp, it is replaced with the
19 * result of the expression new RegExp(regexp). Let string denote the
20 * result of converting the this value to a string. String is searched
21 * for the first occurrence of the regular expression pattern regexp if
22 * regexp.global is false, or all occurrences if regexp.global is true.
24 * The match is performed as in String.prototype.match, including the
25 * update of regexp.lastIndex. Let m be the number of matched
26 * parenthesized subexpressions as specified in section 15.7.5.3.
28 * If replaceValue is a function, then for each matched substring, call
29 * the function with the following m + 3 arguments. Argument 1 is the
30 * substring that matched. The next m arguments are all of the matched
31 * subexpressions. Argument m + 2 is the length of the left context, and
32 * argument m + 3 is string.
34 * The result is a string value derived from the original input by
35 * replacing each matched substring with the corresponding return value
36 * of the function call, converted to a string if need be.
38 * Otherwise, let newstring denote the result of converting replaceValue
39 * to a string. The result is a string value derived from the original
40 * input string by replacing each matched substring with a string derived
41 * from newstring by replacing characters in newstring by replacement text
42 * as specified in the following table:
44 * $& The matched substring.
45 * $
\91 The portion of string that precedes the matched substring.
46 * $
\92 The portion of string that follows the matched substring.
47 * $+ The substring matched by the last parenthesized subexpressions in
48 * the regular expression.
49 * $n The corresponding matched parenthesized subexpression n, where n
50 * is a single digit 0-9. If there are fewer than n subexpressions,
\93$n
53 * Note that the replace function is intentionally generic; it does not
54 * require that its this value be a string object. Therefore, it can be
55 * transferred to other kinds of objects for use as a method.
