Method chaining is a powerful technique in JavaScript that allows multiple functions to be called sequentially on the same object. It’s commonly used in libraries like jQuery and Lodash to perform operations on collections and manipulate DOM elements efficiently. With the introduction of Arrow Functions in ECMAScript 6 (ES6), method chaining has become even more concise and expressive.

In this article, we’ll explore how Arrow Functions can streamline method chaining in JavaScript, providing practical examples for a deeper understanding.

Understanding Method Chaining

Before we delve into Arrow Functions, let’s briefly review what method chaining is and how it works in JavaScript. Method chaining allows multiple methods to be called on the same object in a single statement, with each method returning the object itself. This enables a fluent and concise syntax for performing sequential operations.

Here’s a basic example of method chaining without Arrow Functions:

// Without method chaining
const numbers = [1, 2, 3, 4…
