Syntax §

All syntax related stuff is here

Functions

• Declaration

func function_name(Parameter-list)(Return_type) {
    // function body
}

• Example

func doSomething(num1, num2 int, action string) int {
    return num1 + num2
}

• By default, Go language uses call by value method to pass arguments in function

struct

• struct in Go is a user-defined type that allows to group/combine items of different types into a single type
• It is analogous to classes in OOP (there are no classes in Go btw)
• struct does not support inheritance but supports composition

type Employee struct {
    name, designation string
    id int
}
