We are required to write a JavaScript function that takes in a string which has integers inside it separated by spaces.

The task of our function is to convert each integer in the string into an integer and return their sum.

Example

Following is the code −

const str = '1 5 12 76 2';
const sumStringNumbers = (str = '') => {
   const findSum = (arr = []) => {
      const sum = arr.reduce((acc, val) => acc + val);
      return sum;
   };
   let sum = 0;
   const arr = str
      .split(' ')
      .map(Number);
   sum = findSum(arr);
   return sum;
};
console.log(sumStringNumbers(str));
