I am building a calculator app. Where I store input values in array with operators. e.g

let arr = ['2', '3', '+', '7', '-', '8', '*', '2']

I can't figure out how to handle operator by looping over to get result either 44 or 14 depends on logic.

  • @Andreas depends, if you type it on a calculator it would not wait for order of operations. Commented Jul 10, 2020 at 14:11
  • Eval is not recommended to use Commented Jul 10, 2020 at 14:15
