javascript - How to randomly iterate through an array once, and then repeatedly iterate in that order -

This is my array: arr = [0, 1, 2, 3, 4, 5] I randomly want to iterate for the first time and after that I want to repeat the same (random) order again. How will I do this? I can think that the only way to throw AR is to use it in some way and then it will be repeated gradually. For example:

  newArr = shif (arr); For (j = 0; j & lt; 5; j ++) {for (i = 0; i & lt; newArr.length; i ++)}  

I think Is there any easy, inline way, so that if the item is added to the array then I do not have to reshape (and every time a new array )

Create a second array. Next, populate the array with the random number (ranging from 0 to array.length ). Now make a loop to repeat through the secondary array. Each number in the array corresponds to an index in the array .

Result: You can now randomly iterate without modifying the command through the array array .

Later you can use the splice () function to add to the other array at random points (and push () main To add to the array ).
