How do rest parameters work with arrow functions?

Can you explain how rest parameters work in arrow functions?

Sure! Rest parameters allow you to represent an indefinite number of arguments as an array. In arrow functions, you can use them like this: const myFunction = (...args) => { /* code */ }.

What’s the difference between rest parameters and the arguments object?

The arguments object is an array-like object available within regular functions, but it doesn't exist in arrow functions. Rest parameters, on the other hand, are a true array and can be used directly.

Can you give me an example of using rest parameters in an arrow function?

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

Are there any limitations to using rest parameters?

Yes, you can only have one rest parameter in a function, and it must be the last parameter in the function definition.
