We are required to write a JavaScript function that takes in a string that contains some one-digit numbers in between and the function should return the sum of all the numbers present in the string.
Example
The code for this will be −
const str = 'uyyudfgdfgf5jgdfj3hbj4hbj3jbb4bbjj3jb5bjjb5bj3'; const sumNum = str => { const strArr = str.split(""); let res = 0; for(let i = 0; i < strArr.length; i++){ if(+strArr[i]){ res += +strArr[i]; }; }; return res; }; console.log(sumNum(str));
Output
The output in the console −
