What is the channel pipeline?

It is a data pipeline in which you can write data and read data from it.

Channel is a data communication bridge between goroutine and is thread-safe.

Channel follows the first-in, first-out principle.

Both write and read data will be locked.

Channel can be divided into three types:

Read-only channel, unidirectional channel

Write only channel, one-way channel

Readable and writable channel

Channel can also be divided according to whether there is a buffer or not:

Channel with buffer, which defines the buffer size and can store multiple data

Channel with no buffer can only store one data, and the next data can be saved only when the data is taken out.
