The toolset of the JavaScript developer is ever-evolving and ever-changing. Array manipulation saw dramatic improvements in usability, utility, and readability with the release of the ECMAScript 6 standard in 2015. This update was released with game-changing features like arrow functions, scoped variables like ‘let’ and ‘const’, and many other commonly used tools.

As a developer, I use these features on a regular basis when developing in a Javascript environment, whether that’s a front-end library, such as React or Angular, or on the backend through Node. Most developers have experience with arrow functions and scoped variables, which are incredibly common to see throughout modern code bases. One feature included in ECMAScript 6 is the Spread Operator. While I do not often see it used, it is perhaps my favorite.

In this blog, I will cover the Spread Operator. We’ll talk about what it is and how it’s used to manipulate both objects and arrays. We’ll walk through some examples to help you get started using it in your programming along the way. Let’s jump in.
