hi guys, can you give some recommendation a place to learn javascriprt completely? and i ever hear about extJS, is it javascript too? thanks
I reccomend books from David Flanagan. This is his newest (available in May) http://www.davidflanagan.com/2011/02/javascript-the.html I dont use ExtJS, but is a javascript framework and you can read more here http://www.sencha.com/products/extjs/
try this for javascript http://www.w3schools.com/js/default.asp extjs is for making a desktop environment on a web browser and is not the same as javascript its a different java class by itself
DO NOT USE W3SCHOOLS (read why on http://w3fools.com/) use mozilla MDC - https://developer.mozilla.org/en/JavaScript books: Javascipt, the Good Parts by Doug Crockford is an excellent insight into JS and its quirks. once you have command of that, look at sencha/extjs.
