**Function.prototype.delayCall**

Метод позволяет не вызывать функцию чаще, чем 1 раз в промежуток времени

```js

var block = document.getElementById("black_square");

var handler = function(event) {

    console.log("Handler");

};

handler = handler.delayCall(1000); // не чаще, чем 1 раз в секунду

block.onclick = handler;

```
