I’ve a use-case the place we have to use a javascript object as a key in a Map. If we do not implement a toString() technique we’ll find yourself with [object Object] by default so i got here up with the under sample. Are there any drawbacks to this, or a greater option to obtain this?

var Title = perform(title) {
    this.title = title;
    this.id = Math.random().toString(36).slice(2);
}

Title.prototype.toString = perform() {
    return this.id;
}
