Javascript - Sum solution

Question

I am getting below line in my source file and I would like to sum those values separated by pipe ("|")

There is no limit for the values coming in the line (might be 100 values)

10|20|30|40|[no limit for values] - Separator is pipe "|"

The ouptput would be 100

Please help to write a javascript function for the above query.

Regards Jay

Use `string.split()` to split the string into an array. Use `parseInt()` to convert those strings into numbers. And use `array.reduce()` to add them up. — Barmar, Aug 09 '17 at 11:35

You should take a look at JavaScript's built-in functions: With split you can split your string into an array, with reduce you can 'reduce' your array to a single value, in that case via summation. These two links should provide you enough information for building your code.

You could try something like below:

function sum(value){
  var total = 0;
  var array = value.split(",").map(Number);
  for( var i = 0; i < array.length; i++) {
     total += array[i];
  }
  alert(total);
}
var value = "10|20|30|40".replace(/\|/g, ',');

console.log(sum(value));
