How To Convert Any Function To An Arrow Function In JavaScript
Same results, less code. Learn the process of converting any type of traditional JavaScript function into an arrow function to make your code more compact and powerful.
When it comes to JavaScript, it is no secret that it is a function heavy language. It is full of different ways of using, reusing, passing around functions and more.
And all of this is for a good reason. Functions provide a highly modular way of structuring your application logic. If you change something about your function, you only change the transformation that is happening to the given data.
This data isolation not only makes it easy to write applications, but it also makes your code more testable and robust. Because no matter where and when you run your code, as long as you provide the same inputs, you will receive the same outputs, regardless of your running environment or other variables.

One of the most popular front end libraries, React.js, also introduced something called “Hooks” with React 16.8 to allow front end developers to only use functional programming while developing user interfaces. This change is not minor in any way, as it changed the way you can think about creating user interfaces along with making the overall file structure much more modular and reusable.
When developing the front end of a web application with React.js, there are many times where you find yourself needing a function, but you only need it once. And sometimes these functions are so short that defining and using them with names can feel like writing clunky code. This can be the case, especially if you already know that you can make your code much more concise and legible.
