XOR Color Invert
var color = 0xFFFF00;
function toHex(color) {
return '#' + ('000000' + color.toString(16)).substr(-6);
}
function onClick() {
color ^= 0xFFFFFF;
document.body.style.background = toHex(color);
}
onClick();
document.addEventListener('click', onClick);
Have a look at the slighty different ES6 version:
This is a great trick and a good reason to learn XOR and binary if you don’t already know about those things. The `toHex` function is also kind of snippet worthy in itself.
