Internet Explorer 11 Blob from DataView throws InvalidStateError
var buffer = new ArrayBuffer(8);
var left = new DataView(buffer, 0, 4);
try {
//Throws InvalidStateError in IE 11.
//It does work if we use a specific view like Uint8Array and not the generic DataView contructor.
new Blob([left]);
} catch(ex) {
alert(ex.message);

Quick and dirty way to debug which prop/state changes caused react update
componentDidUpdate: function(prevProps, prevState) {
var differentProps = {};
var differentState = {};
var k;
for(k in prevProps) {
if(prevProps[k] !== this.props[k]) {
differentProps[k] = [prevProps[k], this.props[k]];
}
}
