📘 Class 17

Video Name: Scope with another boring example 🙃

🧑‍💻 Code written in this class

package main

import "fmt"

var (
	a = 10
	b = 20
)

func printNum(num int) {
	fmt.Println(num)
}

func add(x int, y int) {
	res := x + y
	printNum(res)
}

func main() {
	add(a, b)
}

🧠 Key Concepts

1. ✅ Order doesn't matter (for package-level stuff) The order of functions and globally declared variables does not matter in Go. Even if the functions and variables are defined after main(), Go will still recognize and compile everything correctly.

2. 🤓 Go ≠ Functional Paradigm Although Go has borrowed some cool ideas from functional languages (like first-class functions, closures, etc.), Go is not a functional programming language.

3. ⚖️ What paradigm is Go really?

   Go is a multi-paradigm language, but its primary style is imperative and procedural, with struct-based composition over classic OOP.

It's built to be:

✅ Simple

🔍 Predictable

📖 Readable

You can write in a functional-ish style, but Go wasn’t designed for heavy functional abstractions.
