What is the REST operator in programming?

Can you explain what the REST operator is in programming?

The REST operator, often referred to as the spread operator, allows you to expand elements of an iterable (like an array) into individual elements.

How is the REST operator different from the spread operator?

Actually, they are often used interchangeably in JavaScript. The spread operator is used to expand elements, while the REST operator collects multiple elements into a single array.

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

Sure! In a function, you can use it like this: function myFunction(...args) { console.log(args); } This collects all arguments into an array called args.

Are there any limitations to using the REST operator?

Yes, the REST operator can only be used as the last parameter in a function definition, and it cannot be used in certain contexts like destructuring assignments.
