Friends I am now familiar with JSP pages,and wondering how JAVASCRIPT will be useful for me.I am zero in JAVASCRIPT and I am not sure wether I will ever be needing it.
Well I know that JAVASCRIPT can be used to build pages dynamically at the CLIENT site.Right ?
Can some one tell me wether it is useful for me to learn JAVASCRIPT.
Thanks.
I find JavaScript to be VERY useful but it depends on what you are trying to do. As was mentioned Validation,
You could also use it for some of the dynamic features of a form when you don't want to reload the form to have the changes take place. For example cascading list/comboboxes where values change depending upon previous selections, etc.
Also alot of the DHTM(mouseovers, etc) make use of javascript. I would suggest learning it.

It is well worth knowing about- you can do much more with it when you combine it with dynamic server-side stuff than you might expect. For a java programmer it is quite easy apart from the fact it doesn't often hand out helpful debugging information. There are good tutorials at http://www.wsabstract.com
