How do I use default parameters with arrow functions?

How do I use default parameters with arrow functions in JavaScript?

You can set default parameters in arrow functions by assigning values in the function signature. For example: const greet = (name = 'Guest') => Hello, ${name}!;.

Can you give me an example of how that works?

Sure! If you call greet() without an argument, it will return 'Hello, Guest!'. If you call greet('Alice'), it will return 'Hello, Alice!'.

What if I want to use multiple default parameters?

You can do that too! For example: const introduce = (name = 'Guest', age = 18) => My name is ${name} and I am ${age} years old.;.

Thanks! This is really helpful.
