I am trying to convert string to number but I am unable to do that , after passing each number from foreach 

function sum(num){ num.toString().split('').forEach(add); } function add(value , key) { console.log(value); // 2,3 Number(value); console.log(typeof(value)) // string string } sum(23);

In the code - >

After I did Number(value); in function add(value, key) I am still getting string console.log(typeof(value)) // string

    You should do var n = Number(value); console.log(typeof(n)); Commented Jun 22, 2019 at 10:28
  • check this const crossSum = num => String(num).split("").reduce((a,b) => a+Number(b), 0); Commented Jun 22, 2019 at 14:29

You're not assigning it to a new variable / reassigning the variable:

function sum(num){ num.toString().split('').forEach(add); } function add(value , key) { console.log( { value } ); const newValue = Number(value); // or alternatively value = Number(value); console.log( typeof newValue ); } sum(23);
