javascript - trendy again

Javascript is back in shape, with all the buzz about Web2.0 (Thanks to Ajax & Co). So, didn't have to wait too long before we get some techys jumping on the train.

Javascript, programming language? - let's build a library then!

Here we go: http://prototype.conio.net/

Below are a few derived application frameworks derived from prototype:

Ok, looks nice...but...what's the difference between client side languages and server side languages. Well, if you want to use a client side library, you'll need to ask your browser to load it first.

So, you have spent hours retouching your pictures to ensure that your page is under 100k, and then..you are going to load a 200k library to carry on tasks that may require just a couple of lines in javascript.

so.. alittle piece of advice - learn javascript first, before jumping with your two feet in the Web2.0 frenzy.
