Codecademy

"Codeacademy is a website where you can learn the basics of Javascript, which is one of the most used languages on the Internet. "Here's a few screen shots from my first 90 minutes exploring this site."

I have done this for a 1 hr. and  30 mins. so in that time i got to 5. The first section is called "Getting to Know You, Part 1" This lesson is petty short and i have taken some screen shots of the section so you can see.

 

Another tool you can use to practice code writing is Scratch Pad."
