Hooks are used to manage the state of the project. We can use useState. It gives a mechanism to use state and other React functionality without writing a class. Hooks are only worked in the react component, not inside the class.<\/p>\n

How to import hook<\/strong>
\nimport React, { useState } from \"react\";<\/code><\/p>\n

Types of hooks<\/h2>\n
    \n
  1. useEffect hook<\/li>\n
  2. useState<\/li>\n<\/ol>\n

    useEffect hook:<\/strong> UseEffect hook works as componentDidMount, it is mostly used on the page load like fetching data.
    \nimport React, { useEffect, useState } from \"react\";
    \nfunction ListingDetail() {
    \nuseEffect(() => {
    \nfetchListingDetails();
    \n});
    \nconst fetchListingDetails = () => {
    \nconsole.log(\u2018In fetchListingDetails method\u2019);
    \n};
    \n}<\/code><\/p>\n

    useState hook:<\/strong> useState is used to manage the state of an object throughout the component. In the below example, I have initialized the count variable to 0 and increased the count value by one on every click, and set the variable with a new value. This count variable will be updated at every location in the component.
    \nfunction ListingDetail() {
    \nconst [count, setCount] = useState(0);
    \nreturn (
    \n<>
    \n<div>
    \n<p>You clicked {this.state.count} times<\/p>
    \n<button onClick={() => setCount(count + 1)}>
    \nClick me
    \n<\/button>
    \n<\/div>
    \n<\/>
    \n);
    \n}<\/code><\/p>\n
