What is the difference between the spread and rest operators in JavaScript?

The spread operator expands an iterable into more elements, while the rest operator collects multiple elements into an array.

Can you give me an example of each?

Sure! For the spread operator: const arr = [1, 2, 3]; const newArr = [...arr, 4, 5]; For the rest operator: function sum(...numbers) { return numbers.reduce((a, b) => a + b, 0); }

Are they used in the same context?

Not exactly. The spread operator is used in function calls and array literals, while the rest operator is used in function parameters.

Can I use them together?

Yes, you can! For example, you can use the rest operator in a function and then spread the arguments when calling it.
