modeThe above describes the synchronization component. foo () is a synchronous function, that is, the caller of the foo () function must wait until the foo () function is executed before it can go down. When foo () when a function is a function with IO time-consuming operations, asynchronous foo () functions can reduce blocking waits and improve overall performance.To Implement Asynchronous components, you only need to pay attention to the uv_queue_work API of libuv.
