/* * String.match( regexp ) * * If regexp is not an object of type RegExp, it is replaced with result * of the expression new RegExp(regexp). Let string denote the result of * converting the this value to a string. If regexp.global is false, * return the result obtained by invoking RegExp.prototype.exec (see * section 15.7.5.3) on regexp with string as parameter. * * Otherwise, set the regexp.lastIndex property to 0 and invoke * RegExp.prototype.exec repeatedly until there is no match. If there is a * match with an empty string (in other words, if the value of * regexp.lastIndex is left unchanged) increment regexp.lastIndex by 1. * The value returned is an array with the properties 0 through n-1 * corresponding to the first element of the result of each matching * invocation of RegExp.prototype.exec. * * Note that the match 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.
