In this article, we will learn how to play the code generation of go language. Go language code generation is mainly used to solve the problem of programming genericity. The main problem of generic programming is that static type languages have types. Therefore, relevant algorithms or data processing programs need to be copied because of differ ...

Version 1.17 of the Go language has been released, which officially supports generics. Although there are some limitations (for example, you can't export generic functions), you can experience it. My "Go programming mode" series finally has real generic programming, and there is no need to use difficult technologies such as reflection ...

Its definition is as follows: type slice struct { array unsafe.Pointer //Pointer to the array where the data is stored len int //How long is it cap int ...

In this article, we will learn about the three very important operations of map, Reduce and Filter in functional programming. These three operations can make us carry out some data processing very conveniently and flexibly - in most cases, our programs are used to invert data, especially for some business scenarios that need statistics, Map/Red ...
