== Summary ==
In this chapter we have looked at one of the most powerful and frequently used javaScript JavaScript core objects - the String Object. As a JavaScript developer much of your time will be spent validating and manipulating string data entered by web site users. By combining the many methods of the String object it is possible to perform just about any string validation or manipulation tasks imaginable. As with any technology experimentation is the key to getting up to speed on JavaScript Strings so fire up your favorite editor and start trying out the methods described above.
