Refs Hooks

React refs store non-rendering data like DOM node references or timeout IDs, without triggering re-renders. They enable interaction with non-React systems, like browser APIs, aiding integration with external libraries and imperative logic. Serving as an “escape hatch” from React’s standard data flow, refs offer flexibility and enhance compatibility with diverse environments.

  • useRef is used to create mutable references that persist across renders in functional components.
  • useImperativeHandler customizes the instance value that is exposed when using ref with functional components.
const App () =>{
const myRef = useRef(null);
const handleClick = () => {
myRef.current.focus();
};
}

Built-in React Hooks

In React, built-in Hooks are like tools that empower your components with various functionalities. They give you the flexibility to use different features without having to create class components. You can either utilize the hooks provided by React or mix and match them to create custom hooks tailored to your needs. Here’s a list of all the pre-built hooks available in React.

State Hooks

State in React allows a component to keep track of information such as user input or the current state of the component. For instance, imagine a form where you type in your name. State would remember what you typed. Similarly, in an image gallery, state would remember which image you selected to display. It’s like a memory bank for your component to hold onto important data....

Context Hooks

Context in React acts as a global store for sharing data between components, allowing distant components to access this data without the need for prop drilling, thereby simplifying state management and making it more efficient....

Effect Hooks:

Effects in React allow components to interact with and stay synchronized with external systems, such as handling network requests, manipulating the browser’s DOM, managing animations, integrating with widgets from other UI libraries, and working with non-React code. Essentially, effects help components communicate and coordinate with the world outside of React....

Performance Hooks:

To make your React app run faster, a smart strategy is to avoid doing unnecessary tasks. For instance, you can instruct React to reuse previous calculations that are already saved, or to avoid redoing a render if the data hasn’t changed since the last time. This helps your app be more efficient and responsive....

Resource Hooks:

Components in React can access resources without storing them as part of their state. For instance, a component can retrieve a message from a Promise or obtain styling information from a context without needing to manage that data internally. This approach simplifies component logic and promotes more efficient resource utilization....
