As a Vue.js developer, you’re probably always on the lookout for ways to write cleaner, more concise code. Enter the rest and spread operators — two powerful features of modern JavaScript that can help you streamline your Vue.js applications. In this article, we’ll explore what these operators are and how you can leverage them in your Vue.js projects.

What are Rest and Spread Operators?

The rest operator (...) allows you to collect the remaining elements of an array or object into a new array or object. Here's an example:

const [first, ...rest] = [1, 2, 3, 4, 5];

console.log(rest); // Output: [2, 3, 4, 5]
