How to check if second string is subsequence of first string in Node.js

Answer 1

const stringIsSubsequence = (first, second) => {
    let i = 0;
    let j = 0;
   
    while (i < first.length) {
        if (j === second.length) {
            return false;
        }
        if (first[i] === second[j]) {
            i++;
        }
        j++;
    };
   
    return true;
