Function Composition in Javascript - what is it about and why do you need it?

J.R. Sinclair's article discusses function composition in JavaScript, a crucial aspect of functional programming. Function composition involves combining two or more functions into a single function, allowing for a more modular and understandable code approach. Sinclair explains that through composition, we can create complex operations from simpler functions, significantly easing testing and reusability. Moreover, he emphasizes how function composition enhances code readability, as it enables developers to focus on higher levels of abstraction. The article includes examples of function composition in action and outlines the benefits of employing it in various projects. Ultimately, function composition can greatly improve the efficiency and clarity of JavaScript code, which is essential in the programming world. I invite you to read this insightful piece to learn how to incorporate these techniques into your coding practices.
