Example
Do a global search for "man" in a string, and replace it with "person". Then change the regular expression and replace either "man" or "woman" with "person", with the compile() method:
var str="Every man in the world! Every woman on earth!";
var
patt=/man/g;
var
str2=str.replace(patt,"person");
document.write(str2+"<br>");
patt=/(wo)?man/g;
patt.compile(patt);
str2=str.replace(patt,"person");
document.write(str2);
The output of the code above will be:
Every person in the world! Every woperson on earth!
Every person in the world! Every person on earth!
