React useEffect Hook Tutorial for Beginners | Learn 3 Ways to Use useEffect 🚀 Hello Friends! Welcome back to another JavaScript/React tutorial. In my previous video, we have learnt the useState hook. In this video, we are diving deep into the React useEffect hook and breaking down its 3 most important behaviors based on the dependency array. If you get confused about when useEffect runs, why your components re-render, or how to isolate side effects, this step-by-step code-along guide is exactly what you need to clear your concepts! 🕒 What You Will Learn in This Video: What is Mounting? Understand what happens behind the scenes when a React element renders on the UI for the first time. Method 1: Without a Dependency Array – Learn why useEffect runs on every single re-render and how to track component updates using a counter application. Method 2: With an Empty Dependency Array [] – Discover how to make your code run only once during the initial component mount. Method 3: With a Specific Dependency Array [value] – See how to target a specific state variable (like tracking a color-changing button) so your hook runs only when that exact value changes. thankyou ☺️
