Day 7 - The useEffect Hook & Side Effects

React JS Daily Series: Day 7 - The useEffect Hook & Side Effects Welcome to Day 7! We've made it through the first week of our React series. Today we are tackling one of the most powerful (and sometimes confusing) concepts in React: The useEffect Hook. This is how we handle "side effects" in our components, like fetching data from a server or updating the browser tab title. 🚀 What We Covered Today: • What is a "Side Effect" in React? • Importing and writing the useEffect hook • Understanding the Dependency Array (the magic brackets []) • How to control when useEffect runs (on mount, on update, or always) • Writing a cleanup function to prevent memory leaks 📌 Catch up on the series: • Day 6 (Rendering Lists & Keys):    • Day 6 - Rendering Lists & Understanding Keys   • Full Playlist:    / @q-spider   💡 Today's Quick Practice Task: Create a component with a counter state. Use the useEffect hook to automatically update your browser's document title (the text on the browser tab) every time the counter number changes. 🔔 We are just getting started!
