react destructuring code example

Example 1: Object destructuring

Object Destructuring =>
//
   The destructuring assignment syntax is a JavaScript expression that makes it
possible to unpack values from arrays,
or properties from objects, into distinct variables.
//
example:
const user = {
    id: 42,
    is_verified: true
};

const {id, is_verified} = user;

console.log(id); // 42
console.log(is_verified); // true

const Attraction = ({  auth,   auth: { token },  attraction: { id, url_name, name, image_url, average_rating }}) => {  return (    <div auth={auth} key={id}>      <Link token={token} to={`/attractions/${url_name}`} key={id}>        <img alt={name} src={image_url} />        <h1>{name}</h1>      </Link>      <StarRatings rating={average_rating} />    </div>  );};

Example 3: definition destructuring react

Example 4: definition destructuring react

Example 5: definition destructuring react

class Attraction extends React.Component {  render() {    const {      auth,      auth: { token },      attraction: { id, url_name, name, image_url, average_rating }    } = this.props;return (      <div auth={auth} key={id}>        <Link token={token} to={`/attractions/${url_name}`} key={id}>          <img alt={name} src={image_url} />          <h1>{name}</h1>        </Link>        <StarRatings rating={average_rating} />      </div>    );  }}
