Here’s what I’d like you to know upfront: this is a hard problem. If you’ve landed here because you’re hoping to be pointed at a tool you can run that tells you exactly what CSS you can delete from your project, well… there are tools out there, but I’m warning

We make use of state to keep track of application data. States change as users interact with an application. When this happens, we need to update the state that is displayed to the user, and we do this using React’s setState.

Testing applications is crucially important to ensuring that the code is error-free and the logic requirements are met. However, writing tests manually is tedious and prone to human bias and error. Furthermore, maintenance can be a nightmare, especially when features are added or business logic is changed. We’ll learn how
requestAnimationFrame should be easy, but if you haven’t read React’s documentation thoroughly then you will probably run into a few things that might cause you a headache. Here are three gotcha moments I learned the hard way.

That’s why we’re going to focus on testing in this post, specifically for React applications. By the end, you’ll
I’ve been auditing a ton of CSS lately and thought it would be neat to jot down how I’m going about doing that. I’m sure there are a million different ways to do this depending on the size and scale of your app and how your CSS works under the

Working with data in React is relatively easy because React is designed to handle data as state. The hassle begins when the amount of data you need to consume becomes massive. For example, say you have to handle a dataset which is between 500-1,000 records. This can result in massive
There is a sentiment that leaving math calculations in your CSS is a good idea that I agree with. This is for math that you could calculate at authoring time, but specifically chose not to. For instance, if you needed a 7-column float-based grid (don’t ask), it’s cleaner and more
