** Step 1: What is a Function?​

Imagine you have a robot assistant. Instead of telling it every little step, you just say: ‘Make me a sandwich!’ and it knows what to do. A function is like that—it’s a set of instructions that does something when you call it."*

Here’s how you write a function in JavaScript:

"This function does one thing: it returns the text 'Hi, Great to have you here !' whenever we use it."

function greet() {
    return "Hi, Great to have you here!";
}
console.log(greet());

Step 2: Functions with Parameters​

What if we want to greet different people instead of always saying the same thing?

That’s where parameters come in! They allow us to pass information to the function."*

function greet(name) {
    return "Hi " + name + ", nice to meet you!";
}

console.log(greet("Enoch"));


Now, instead of always greeting the same person, we can pass different names."

Step 3: Returning Values in a Function​

A function can return a result that we can store and use later. Let’s create a function that doubles a number.

function doubleMe(number) {
    return number * 2;
}
let result = doubleMe(5);
console.log(result);

Step 4: Functions with Multiple Parameters​

function addNumbers(num1, num2) {
    return num1 + num2;
}

console.log(addNumbers(3, 7)); // Output: 10
console.log(addNumbers(15, 5)); // Output: 20


Step 5: Functions That Return Multiple Values​

One solution is to return an object:

function getUserInfo(name, age) {
    return {
        username: name,
        userAge: age
    };
}
let user = getUserInfo("Enoch", 39);
