Javascript Code Function Array Shuffled to Mix Up order of Array Elements

const arr_shuffled = (array) => Javascript Function Code to Mix Up the Order of Elements in a Javascript Array

The Javascript code below will take an array and mix up or shuffle the order of the elements within the array.

/* ----------------------------- REORDER AND SHUFFLE AN ARRAY ------------------------------- */ const arr_shuffled = (array) => { const newArray = [...array]; for (let i = newArray.length - 1; i > 0; i--) { const j = Math.floor(Math.random() * (i + 1)); [newArray[i], newArray[j]] = [newArray[j], newArray[i]]; } return newArray; };

Now that the array has been shuffled you can grab the first element and then delete that element of the array to ensure it is only used once via ...

arr = arr_shuffled(arr); let firstelem = arr(arr[0]); arrurls.shift();
