What are the differences between rest and spread operators in JavaScript?

Can you explain the differences between rest and spread operators in JavaScript?

Sure! The rest operator collects multiple elements into an array, while the spread operator expands an array into individual elements.

Can you give me an example of how to use the rest operator?

Of course! Here's an example: function myFunction(...args) { console.log(args); } will collect all arguments into the args array.

And what about the spread operator?

The spread operator can be used like this: const arr1 = [1, 2]; const arr2 = [...arr1, 3, 4]; which results in arr2 being [1, 2, 3, 4].

Are there any specific use cases for each?

Yes! Use the rest operator for function parameters to handle variable arguments, and the spread operator for array manipulation or merging.
