split string number to be 2 each strings in array

Question

how to split a string number to be arrays example :

var str = "124590"
var str2 = "12459010"

// output:
["12", "45", "90"]
["12", "45", "90", "10"];

and how to make those array strings to be number also in the array, and if we use regex, could it work? thx

If you have written code for this that you can't get to work, then you have come to the right place. Just [edit] the question and add the relevant parts of your code into it, because without that we cannot help. Also please see **[ask]**. — Peter B, Oct 29 '18 at 12:07

You can use something like this to split it every 2 characters:

var str = "124590";
var str2 = "12459010";

let regex = /\d{2}/g;
let array = str.match(regex);
let array2 = str2.match(regex);

console.log(array);
console.log(array2);

\d matches any digit, {2} makes sure it matches twice. The g part makes sure it matches every occurance and doesn't stop at the first match.

A string is basically an array of characters, so you can loop through it:

var str1 = "124590"

function splitMe(str) {
  var arr = []
  for (let i = 0; i < str.length; i++) {
    arr.push(str[i]+str[i+1])
    i++
  }
  return arr
}

console.log(splitMe(str1))
console.log(splitMe("1241389572489651"))
