Issue này là một checklist tiến độ của Stage 4 thay vì một thay đổi mã đơn lẻ. Hãy bắt đầu với kế hoạch và các bài kiểm thử test262 được liên kết, các báo cáo triển khai cho JavaScriptCore, SpiderMonkey, XS và V8, cùng các tham chiếu ecma262. Được xem là hoàn tất khi các yêu cầu và mục phản hồi còn lại trong giai đoạn proposal đã được giải quyết.
