Script Preparation code:

var canvasOne = document.getElementById("canvasOne");
var ctxOne = canvasOne.getContext("2d");

var canvasTwo = document.getElementById("canvasTwo");
var ctxTwo = canvasTwo.getContext("2d");

var canvasThr = document.getElementById("canvasThr");
var ctxThr = canvasThr.getContext("2d");

var canvasFour = document.getElementById("canvasThr");
var ctxFour = canvasFour.getContext("2d");
