raf.js

A simple script with a few niceties that allows for multiple requestAnimationFrame calls, and FPS pinning.

How it works

The script polyfills rAF if required, then overloads requestAnimationFrame and cancelAnimationFrame with a process that allows multiple frames to be queued up for rAF to run.

This is useful if there are multiple animations running on the page, you want all the callbacks to happen at once, and not on multiple rAF calls. This script is meant as a drop-in solution to that problem.

var Vector = function(x, y) {
  this.x = x || 0;
  this.y = y || 0;
};

// return the angle of the vector in radians
Vector.prototype.getDirection = function() {
	return Math.atan2(this.y, this.x);
};

// простая чистая функция, которая возвращает сумму аргумента и 10
const add = (n) => (n + 10);
console.log('Simple call', add(3));
// простая функция, принимающая другую функцию и
// возвращающая её же, но с мемоизацией
const memoize = (fn) => {
  let cache = {};
  return (...args) => {
    let n = args[0];  // тут работаем с единственным аргументом
    if (n in cache) {
