• Functions

    A function in programming is a task you the program to perform. It tells the computer what to do and how to do it when it runs a certain program. It's kind of like telling a robot what to do. For example, if you want the robot to make something for you, you would give it instructions or write down a recipe on how to make that thing. That's what functions are like: instructions for the computer on how to make something happen.

      • Defined Functions

      • Go

        Example of function in go.
        package main

import "fmt"

func addition(a int, b int) int {
	return a + b
}

func main() {
	fmt.Println(addition(1, 2)) // 3
}

      • Anonymous Functions

      • Go

        Example of anonymous function in go.
        package main

import "fmt"

func main() {
	func(a int, b int) {
		fmt.Println(a + b) // 3
	}(1, 2)
}

      • Variable Functions

      • Go

        Example of variable function in go.
        package main

import "fmt"

func main() {
	var addition = func(a int, b int) int {
		return a + b
	}

	fmt.Println(addition(1, 2)) // 3
}
