What are default parameters

What are default parameters?

Default parameters allow you to set default values for function parameters if no argument is provided when calling the function. This helps in avoiding undefined values.

Example:

function greet(name = 'Guest') {
  console.log('Hello, ' + name);
}
greet();  // Output: Hello, Guest
greet('John');  // Output: Hello, John
