What is the channel in golang

This article is to share with you about what channels are in golang. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The channel type in golang is a special type with the name chan. At any time, there is only one goroutine access channel for concurrency and data acquisition, and the goroutine can communicate through the channel. We can create a goroutine with the go keyword.

The channel itself is synchronous, and the sending and receiving data of the channel are synchronous by default, and follow the first-in-first-out rule to ensure the order of data transmission.

The channel is divided into two-way channel and one-way channel.

Two-way channel:

Chan1: = make (chan int, 10)

One-way channel:

# one-way write-only channel, 10 indicates the capacity of the channel chan2: = make (chan)
