Function to check if 2 objects collide. Very useful for games.

arguments:

a: object 1 x

b: object 1 y

This function checks if a canvas pixel is black.

This is very useful for making pixel-perfect collisions in a javascript game.

argument x and y are for the coordinates of said pixel.

argument c is for the canvas context.

This is a function to calculate the appropriate unit to describe a file size. If you want a fancier function, try this function: https://gist.github.com/2202887 by @vitronprince

A function to get rid of the stupid "Math" object once and for all!

It allows this sort of syntax:

 myVariable = floor(myVariable)
 myOtherVariable = random()

I always thought there was a better way to access the dom. This is a tool that allows you to use extremely simple syntax to access dom elements. It makes an object with the name of your choice (I chose "$") that contains a reference to all elements that have an id.

example:

You can even choose to use an object that already exists (I chose "document" because it makes sense)

Adds vendor prefix when needed.
