Features of Go

1. If you import a package or declare a variable, then haven't used it on your program, an error will be caused.

2. They call threading processing Goroutines. It's super easy to use, read more about it: https://pragmacoders.com/blog/multithreading-in-go-a-tutorial

3. There has no such a thing called named arguments in the function definition.

4. There has no such a thing called private field (or arguments) for a struct (or class) . If you need a struct that has a lot of private variables inside of that struct (or class), you need to return a point of a new struct.

5. If you don't give a point of a struct to your struct function, you won't be able to use it as a normal class as you would do in other programming languages. (Because you can't really change the in-class variable in that case)

6. There is no such a thing called default arguments in the function definition or struct definition.
