suspend function trung tâm trong coroutine Đối với 1 lập trình viên Mobile nói chung, và Android nói riêng, trước đây đối với mình, RxJava, RxKotlin, RxAndroid nói chung Rx style và reactive là thứ gì đó tuyệt vời để asynchonous task

Từ khi coroutines ra đời, các lập trình viên Android chuyển sang dùng nhiều hơn vì nó dễ dùng hơn Rx, vì Rx dùng sâu khá khó nuốt.

Đối với coroutine thì các bạn khá dễ dùng rồi, cũng như lợi ích của nó rồi, trong bài viết này mình sẽ không nói tới cách dùng và lợi ích của nó nữa mà phân tích kỹ hơn về vấn đề suspend function

Có thể nói suspend function là trung tâm trong vũ trụ Coroutine.

Không giống như function thường, suspend function không block bất kì thread nào mà nó chạy trên đó, nói thuần tiếng việt nó là function có khả năng tạm dừng và tiếp tục,và huỷ và nó hoàn toàn non-blocking...
