At the beginning, you will learn all the basics about Golang. Define variables, call functions, and some basic knowledge, and then learn flow control, arrays, slices, mappings, and structures.
The concurrency of Golang is realized through Goroutines. The Goroutine is equivalent to a lightweight thread, and it can work concurrently. Golang also provides channels for communication between multiple coroutines.
Learn how to control the flow of your code with if, else, for loops, switches and defers.
