I really need to learn professional javascript in two days because I am gonna have to hit the ground running (real world project). I have little which can be approximated to no knowledge of JavaScript or 开发者_JAVA百科website development. Any help would be appreciated greatly.

Seriously, two days is about enough to get a feel for the basics. It's nowhere near enough time to get to "professional" level (whatever that means exactly). The more experience you have with other languages, the easier it will be, though.

Don't cram for a programming language, especially learning it professionally, unless you have previous programing experience.

Go through video lectures by Douglas Crockford at http://yuiblog.com/crockford/. You could be able to get rid of some assumptions, misconceptions and pick up some really good concepts in less than 10 hrs of video.

Nevertheless, it is indeed a great place to start.

If you need to learn JavaScript, you can follow these courses if you have little previous programming experience. They are interactive and you can code all the examples in the explorer (and they are free).

1 - JavaScript Fundamentals
2 - JavaScript

And finally, a library called jQuery to make a little bit easier JavaScript programming.

3 - jQuery

This won't take you to days, but is a good beginning to be a JavaScripter.

Good luck.
