You can easily find information with varying degrees of correctness about “how-to” with JavaScript. I want to make a case for why-to learn to write in JavaScript. I also want to note that, if you’re in a place like I was just a few years ago with JS, you might not actually know JS yet.

There are a seemingly increasing number of efforts with the purpose of allowing programmers to write in some other language, like Java, CoffeeScript, C, etc. and then have a program turn that code into JavaScript for us.
