A way to mix an array in JavaScript.

mixArray.js

// For production use i recommend: https://phuoc.ng/collection/1-loc/shuffle-an-array/

// function
function mixArray(array) {
	let newArray = [],
		maxRandNbr = array.length;

	for (let i = 0; i = maxRandNbr; i++) {
		randNbr = Math.round(Math.random() * (maxRandNbr - 1));

		let index = array.indexOf(array[randNbr]);
		newArray.push(array[randNbr]);
		array.splice(index, 1);

		maxRandNbr--;
	}

	return newArray;
}

// example
var letters = [
	'A',
	'B',
	'C',
	'D',
	'E',
	'F'
];

console.log(mixArray(letters));
