References Everywhere A variable in JavaScript is simply a label that references a value in memory somewhere. These values can be primitives like strings, numbers, and booleans. They can also be objects or functions. Notice that the two boolean variables point to the same value in memory. This is because primitives are immutable and so the VM can optimize and share a single instance for all references to that particular value.The Best Way to Learn JavaScript | Nettuts+
JavaScript is the language of the browser (not exclusively these days, though). It’s primary purpose is to add interactivity to an otherwise static page. In the browser, it’s not going to replace PHP or Ruby for you. It’s not even going to replace your HTML or CSS; you’ll use it in conjunction to them. Also, it isn’t as terrible to learn as you might have thought or heard. One more note: you’ve heard about jQuery, which is probably the most widely-used JavaScript library.
First let's create a simple constructor function with a prototype. This is the closest thing to a class you're going to find in native JavaScript. It's extremely powerful and efficient, but doesn't quite work like you would expect if coming from a language with classes. Now let's define a new class of objects called Squares that inherit from Rectangles. To do inheritance, the constructor's prototype has to inherit from the parent constructor's prototype . Here we're overriding getPerimeter to make it slightly more efficient and to show how to override functions.

Why Ruby Ok, I'll admit, I used to be a ruby guy. I didn't so much do rails, but I loved the ruby language. I read the pickaxe book, attended dallasrb, tried to start my own ruby based company, failed, and finally taught ruby to home-school kids.
