Question

I want to create a canvas element and get it’s context. I tried everything, but can’t get rid of the buffer variable. It’s driving me insane. Can you help me?

(function(buffer){
    document.body.appendChild(
        buffer=document.createElement("canvas")
    )
    canvas=buffer.getContext("2d")
})()

What’s wrong with the variable? Anyways, you can do:

var canvas = document.body.appendChild(document.createElement("canvas"))
              .getContext("2d");

since Node.appendChild returns the node that was appended.
