React Best Practices: Pro Tips for Clean and Efficient Code

React is a widely-used JavaScript library for building user interfaces, originally developed by Facebook. It’s a favourite among developers for creating both web and mobile applications. In this blog, we’ll go over some essential best practices for working with React, explained in a simple and easy-to-understand way.

Use Code Splitting for Faster Apps

Code splitting helps you load only what the user needs, making the app faster. You can use React.lazy to split code and load parts of it only when needed, like when the user navigates to a certain page.

Instead of writing each route separately, you can define an array of route…
