A systematic review of Golang knowledge, today summarizes some of the characteristics of the channel and some simple implementation.Don ' t communicate by sharing memory;share memory by communicating. 1, the channel type itself is concurrency-safe,

As is known to all, the Golang map is non-coprocessor safe (go1.6 version, after go1.6 read security), and the need for concurrent read and write map should be very common. Examples are as follows: package mainimport "fmt"func main() { a :=
