Here's an example of how to use default function parameters:


function greet(name = 'Guest', greeting = 'Hello') {
    return `${greeting}, ${name}!`;
}

console.log(greet()); // Output: Hello, Guest!
console.log(greet('Alice')); // Output: Hello, Alice!
console.log(greet('Bob', 'Good morning')); // Output: Good morning, Bob!
