Tip: gprof generates a large amount of profiling data. If you want to check the data, you 'd better redirect the output to a file.

function is a string that matches the pattern. The next argument is a string that matches the subexpression in the pattern, and can have 0 or more of these parameters. The next argument is an integer that declares where the match appears in the Stringobject. The last parameter is the stringobject itself. The result is a string value that replaces each matched substring with the corresponding return value of the function call. function as a parameter can be more complex operations.Example 7:Copy

ECMAScript v3 stipulates that the parameter replacement of the replace () method can be a function rather than a string. In this case, each match calls the function, and the string it returns is used as the replacement text. The first parameter of the function is a string that matches the pattern. The next argument is a string that matches the subexpression in the pattern, and can have 0 or more of these parameters. The next argument is an integer that declares where the match appear

re =/the/g;//create regular expression patterns.
r = ss.replace (Re, "a");//Replace "the" with "a".
return (R);//returns the replacement string.

Alternatively, the Replace method can also replace a subexpression in a pattern. The following example shows each pair of words in a swap string:
function Replacedemo () {
var R, re; Declare a variable.
var ss = "The rain in Spain falls mainly in the plain.";
