JavaScript Coding Challenge #2: Add all Integer in a string using JavaScript.

Input : A single string "1bn22vg4n62"

Output : 89

Problem : Add all Integer in a string using JavaScript.

---

let s = '1bn22vg4n62';                //Input String
temp = "";                       //temp var to capture digit from string
sum=0;                               //sum variable to add
for(let i=0;i<s.length;i++){

  if(!isNaN(parseInt(s[i]))){    //logic to check char in string is digit
    temp+=s[i];                  //if true add char to temp string
  }
  else{
    sum+=parseInt(temp);         //if char in string is char- add to sum after 
                                 //converting into integer
    temp="0"                     //setting temp to 0 to neglect effect
  }
}
console.log(sum+parseInt(temp));  
//89

Great.
You can do this in a single line of code, but that is a little harder to read.

const result = '1bn22vg4n62'.match(/\d+/g).reduce((acc,e)=>acc+parseInt(e),0);
console.log(result) // 89

yes I'd have done the same and no, I don't believe this is harder to read than the posted code :)

[Ritik Rana]

Great. That can be done. 👌👌
but they are 2 lines.😉😁✌

[Kafil]

haha 😊

Great Rabei . Just uploading problem that I found more interesting while solving coding problems. I code at HackerRank

[Ritik Rana]

yes my bad. they have to be treated as one digit.✌✌✌

[Kafil]

Then I should change my code to this :

console.log('1bn22vg4n62'.match(/\d/g).reduce((acc,e)=>acc+parseInt(e),0)) //17;
