Learn React Hooks: useEffect - Simply Explained!

In this video we will learn about React hooks, starting with useEffect. This powerful React hook will allow you to have side effects inside of functional components, and will allow you turn your stateful React applications into complex ones. You will learn how to create side-effects using useEffect, how to set the dependency array to have your effect listen to what it should, and how to run cleanup functions when it's time to cleanup.
In this new React world, hooks are here to stay, so it's best to learn them! In this tutorial I demonstrate the useEffect React hook, and I explain it very simply and in a way that is easy to understand. Enjoy!

Hey everyone! I just launched 🚀 Project React, which is a course that teaches you React by building a real-world project. It goes way beyond what you see in these videos and walks you through step-by-step on how to build a big and complex application with React! You can check it out here: cosden.solutions/project-react
