What Is React Hooks ?
Alright Imagine you are building something with React. A popular tool for making interactive websites. A while back they introduced a cool feature called “hooks.” React Hooks are like power-ups for your code especially when you’re using functional components think of them as building blocks for your website.
So these hooks are kind of like special tools that help you manage things more easily. For example keeping track of information that might change or handling when your website needs to do something in response to a user’s action like clicking a button.
In our journey through this blog we’ll talk about some of these hooks that lots of developers find super handy. And to make it even more awesome we will use simple examples that anyone can understand!
What Is UseState Hook ?
Imagine you are building a website and you want to keep track of something that might change. Maybe it’s the number of likes on a post or the text in a search bar. This is where the useState hook comes to the rescue!
In simpler terms useState is like a magical container where you can store and retrieve information in your code. It’s like having a special pocket where you can keep things and check or update them whenever you want.
What Is UseEffect Hook ?
you are building a React component and there are times when you want to do something special when the component first loads or maybe when something in the component changes. This is where the useEffect hook comes into play.
In Simple terms useEffect is like a sidekick that helps your component do extra tasks. Maybe you want to fetch data from a server, update the title of the webpage or perform some cleanup when the component is about to disappear. useEffect is your go-to tool for these scenarios.
What Is UseContext Hook ?
Imagine you are working on a big project with lots of different components and you need to share some information between them like a theme or a users authentication status. This is where the useContext hook becomes your best friend.
In simple terms useContext is like a messenger that helps different parts of your app communicate. It allows you to access and use information that is shared across multiple components without passing it down through each level.
What Is UseReducer Hook ?
Imagine you have a component that needs to manage a more complex state with various actions. This is where the useReducer hook comes into play. In simpler terms useReducer is like having a plan or a set of instructions to handle changes in your component state in a more organized way.
What Is UseCallback Hook ?
you have a React component and within it you define functions that might change when the component re-renders. Now if you pass these functions as props to child components those child components might re-render unnecessarily. This is where the useCallback hook steps in.
In simple terms useCallback is like a memo pad for your functions. It helps you memoize (remember) functions so that they don’t change unless their dependencies change preventing unnecessary re-renders.
What Is UseMemo Hook ?
Imagine you have a component that performs some heavy calculations or computations. Now if these calculations are not dependent on changes in certain values. you wouldn’t want to redo them every time your component re-renders. This is where the useMemo hook comes into play.
In straightforward terms useMemo is like having a cache for your expensive calculations. It helps you remember the result of a computation and only recompute it when the dependencies change.
What Is UseRef Hook ?
Imagine you are working on a React component and you need to keep track of something that persists across renders but doesn’t cause a re-render when it changes. This is where the useRef hook comes in handy.
In simple terms useRef is like having a sticky note that stays the same between renders. It’s great for holding onto values or references that you want to persist without triggering a re-render.
What Is UseLayoutEffect Hook ?
Imagine you have a React component and you want to perform some actions immediately after the browser has painted to the screen. This is where the useLayoutEffect hook comes into play.
In simple terms useLayoutEffect is quite similar to useEffect but it runs synchronously immediately after all DOM mutations. It’s like having a special moment right after the browser has made changes to the layout making it ideal for tasks that need to be handled before the next paint.
What Is UseDebugValue Hook ?
Imagine you are developing a custom hook in React and you want to provide additional information or labels to help developers understand the purpose or state of that hook when inspecting it in React DevTools. This is where the useDebugValue hook comes into play.
In simple terms useDebugValue is like attaching a post-it note to your custom hook providing helpful debugging information for developers.
