Summing array of string numbers using JavaScript

Problem

We are required to write a JavaScript function that takes in an array that contains integers and string numbers.

Our function should sum all the integers and string numbers together to derive a new number and return that number.

Example

Following is the code −

 Live Demo

const arr = [67, 45, '34', '23', 4, 6, '6'];
const mixedSum = (arr = []) => {
   let sum = 0;
   for(let i = 0; i < arr.length; i++){
      const el = arr[i];
      sum += +el;
   };
   return sum;
};
console.log(mixedSum(arr));
