코드리뷰 부탁드리겠습니다.

function solution(str, list) {
    let mustWord = str.split(''); // c, b, a
    let fullWord = list.split('');

    while (fullWord.length !== 0) {
        if (mustWord[mustWord.length-1] === fullWord[fullWord.length-1]) {
            mustWord.pop();
            fullWord.pop();
        } else {
            fullWord.pop();
        }
    }

    return mustWord.length !== 0 ? "NO" : "YES";
