How to remove a pair of the same adjacent characters from a string in Node.js

Answer 1

function removeAdjacentPair(s) {
    for (let i = 0; i < s.length - 1; i++) {
         if (s[i] == s[i + 1]) {
             s = s.slice(0, i) + s.slice(i + 2);
             if (i !== 0) i--;
         }
    }
    return s;
}


let s = "aabcccdeeffffffgach";

s = removeAdjacentPair(s);

console.log(s)
