How to **correctly** debounce an event that will be triggered many times with identical arguments.

debounce.js

const debounce = function(fn, duration) {

	let timeout = null

	return (...args) => {

		clearTimeout(timeout)

		timeout = setTimeout(() => fn(...args), duration)

	}

}

Example:

const fn = (text) => console.log(text)
const dfn = debounce(fn, 200)

dfn('hello')
dfn('hello') // hello
