JavaScript Tutorial 1.3: Introduction to External Input

In this tutorial, we examine one way to receive and play with data given to us from the user rather than data we explicitly include ourselves.

I apologize for the lack of music in this and subsequent tutorials; while Beethoven’s almost always a good listen, adding sound to the video was drastically reducing its quality. Hey, if you feel the music helped, why not throw it on while you read?

There are a few grammatical mistakes, as well as my first typing mistake (bummer…), and for these I apologize.

Somewhere in there, you’ll notice that JavaScript isn’t the greatest handler of multiplication problems, but no worries, I’ll explain why this is as well as how to alleviate the problem in a future tutorial.

A little fast on some of it. I know the video can be replayed, but you really need to give pause at certain times for the watcher to absorb what he/she’s just learned.

You answered your own question, mate; I want to get as much as I can into each tutorial, so I don’t pause for too long; there is, of course, a pretty little button for absorbent watchers to do just that…
