Can I use the rest operator in arrow functions?

Can I use the rest operator in arrow functions?

Yes, you can use the rest operator in arrow functions to gather remaining arguments into an array.

Can you show me an example?

Sure! Here's an example: const sum = (...numbers) => numbers.reduce((acc, num) => acc + num, 0); This function sums all the numbers passed to it.

What if I want to use it with other parameters?

You can mix regular parameters with the rest operator. For example: const greet = (greeting, ...names) => names.map(name => ${greeting}, ${name}!); This will greet each name with the provided greeting.

Are there any limitations I should be aware of?

The main limitation is that the rest operator must be the last parameter in the function definition.
