Class StringBuilder

public class StringBuilder
extends java.lang.Object

A string builder class

+= operator is faster in Firefox and Opera. Array push/join is faster in Internet Explorer

Even with this wrapper, which costs some time, this is faster in Firefox than the alternative Array concat in all browsers (which is in relation to IE’s performance issues only marginal). The IE performance loss caused by this wrapper is not relevant.

So this class seems to be the best compromise to handle string concatenation.
