Backspace String Compare

LeetCode題目: 844. Backspace String Compare

My solution:

/**
 * @param {string} s
 * @param {string} t
 * @return {boolean}
 */
let backspaceCompare = (s, t) => {
    while(s.includes('#')) s = s.replace(/^#|\w#/g, '');
    while(t.includes('#')) t = t.replace(/^#|\w#/g, '');
    return s === t;
};
