Base64 String to Float32Array in Javascript, good for WebGL

b64_to_float32Array.js

var blob	= window.atob("AAAAAAAAAAAAAAAAAACAPwAAAAAAAAAAAAAAAAAAgD8AAAAA"),	// Base64 string converted to a char array
	fLen	= blob.length / Float32Array.BYTES_PER_ELEMENT,						// How many floats can be made, but be even
	dView	= new DataView( new ArrayBuffer(Float32Array.BYTES_PER_ELEMENT) ),	// ArrayBuffer/DataView to convert 4 bytes into 1 float.
	fAry	= new Float32Array(fLen),											// Final Output at the correct size
	p		= 0;																// Position

for(var j=0; j < fLen; j++){
	p = j * 4;
	dView.setUint8(0,blob.charCodeAt(p));
	dView.setUint8(1,blob.charCodeAt(p+1));
	dView.setUint8(2,blob.charCodeAt(p+2));
	dView.setUint8(3,blob.charCodeAt(p+3));
	fAry[j] = dView.getFloat32(0,true);
}
console.log(fAry); //Float32Array(9) [0, 0, 0, 1, 0, 0, 0, 1, 0] - Three Vectors to create a triangle for WebGL
