Retrieving Digits into an Array - JavaScript

Question

I am doing a JavaScript, trying to retrieve the user's numerical input, and store the input's digits as an array.

I managed to retrieve the user's input using DOM, but, how can I store the digits into an array?

Why not post the code you have, and an example of what output you want ? — adeneo

Either input.split() or input.split(",") depending on what your input is — H77

If you want to obtain an array of numbers, one solution is to use Array.from method and map array items to numbers.

let number=1234;
let array=Array.from(number.toString()).map(Number);
console.log(array);

If you want to store singular digits, you could use .split('')

userInput = '42';

console.log(userInput.split(''));

what you can do here is simply:

userInput1 = '42';
userInput2 = '43';
const inputArray = [userInput1, userInput2]

For an array of number:

var input = "123456789";
var array = input.split('')
for(var i = 0; i <array.length; i++) { array[i] = +array[i]; } 
console.log(array)

The operation +array[i] is just a quick way to do the number conversion.

If you want the array of chars remove the for loop from the code
