Yesterday, I went home by car and punched in a force buckle on the car. After I finished, I was bored. I saw that I had collected Akka before. I vaguely remember that it was an execution unit smaller than a thread (that's what I understood at that time). In addition, I learned from Golang before and saw the way that Goroutine can handle request ...

Traversal query Take the string slice as an example to judge whether a string is included in the string slice. // ContainsInSlice determines whether ...

Pointer type Before formally introducing the unsafe package, we need to focus on the pointer types in the Go language. When I started learning programming as an undergraduate, my first language was c. After that, I learned C + +, Java and Python. These languages are very powerful, but they are not as "simple" as C language. Unti ...
