JavaScript is a versatile language with many powerful features, and two of the most useful are the rest and spread operators. Individually, these operators offer great flexibility for handling function parameters and arrays. But when combined, they can truly take your JavaScript skills to the next level.

In this article, we’ll explore how you can combine rest and spread operators to simplify array operations in JavaScript.

Understanding Rest and Spread Operators

Before we dive into combining them, let’s briefly recap what rest and spread operators are and how they work.

• Rest Operator (…): The rest operator allows you to represent an indefinite number of arguments as an array within a function. It gathers all remaining arguments into an array, making it easier to work with functions that accept a variable number of parameters.
• Spread Operator (…): The spread operator, on the other hand, allows an iterable such as an array to be expanded into individual elements. It’s commonly used to make copies of arrays, concatenate arrays, or pass elements of an array as arguments to a…
