Go: profiling or basic profiling of CPU usage
- go
In addition to unit test testing and coverage measurement in go , this programming language is capable of profiling the efficiency of the code by analyzing it in a very detailed way. This is quite useful to find bottlenecks or very expensive parts of the code, which are called nu...

Go: race conditions on goroutines and mutexes
- go
In past posts I talked a bit about goroutines, deadlocks and channels . But there is another quite interesting issue about goroutines that stands out when we use asynchrony and there are many functions accessing data at the same time and. Multiple functions reading and writing th...

- go
So far I have explained how to run a goroutine, execute code concurrently with the goroutines and wait for them to finish executing but our goroutines can’t do anything else, they can’t cooperate with each other to speed up the processes.
Imagine you have a web sc...

Go: package import and module management
- go
In go you can consider a package as all the files contained in a directory and a module as a collection of packages. To use the code of a package we need to import it, however, in Go there are no relative module imports. Before Go 1.8, to import packages (there were no modules) i...

Go: Structs, inheritance, polymorphism and encapsulation
- go
As I already mentioned to you in the introduction to the Golang or Go programming language , this language does not have a reserved word for dealing with classes, but uses structs to emulate features such as inheritance, polymorphism, encapsulation and other properties of classes...

Golang maps or dictionaries
- go
In the go programming language, a map or hash table is the equivalent of a dictionary; they have a key that is related to a value. The key and value can be of different data types, but all keys must be of a single type and all values must be of the same type.
Hey! did you kno...
