Replace multiple characters in one replace call

Here is another version using String Prototype. Enjoy!

String.prototype.replaceAll = function(obj) {
    let finalString = '';
    let word = this;
    for (let each of word){
        for (const o in obj){
            const value = obj[o];
            if (each == o){
                each = value;
            }
        }
        finalString += each;
    }

    return finalString;
};

'abc'.replaceAll({'a':'x', 'b':'y'}); //"xyc"
