Destructuring works similarly in class components, with slightly different syntax. Here you destructure props in the render() function.,We can make this code even simpler by destructuring the auth and attractions props like so:,Destructuring our props lets us drop all of the props.

Imagine you have a person object with the following properties:

const person = {
   firstName: "Lindsay",
   lastName: "Criswell",
   city: "NYC"
}

I don't know React but destructuring the arguments should be something like the following,New to react world, trying to learn destructuring, have been reading about it but stuck here, if i do it like this function MList({action}) { // const data = [action];} i am just getting 'cameras'. So how to destructure and get same result as with props below this is Mcard.js:,Connect and share knowledge within a single location that is structured and easy to search.

I don't know React but destructuring the arguments should be something like the following

function MList({
   action,
   ...tail
}) {

   const initialize = () => {
      const data = tail[action];

      if (!data || data.length < 1) {
         return;
      }
      data.map(({
         name,
         ident
      }) => {
         collapseStates["" + name + ident] = false;
         return;
      });
      setCollapseS(collapseS);

You can use nested destructuring to get person properties:

const {
   person: {
      name,
      age,
      skill
   }
} = props;

This is a huge upside in React when you’re passing down props. Once you take the time to destructure your props, you can get rid of props / this.props in front of each prop.,Destructuring in React is useful for both functional and class components but is achieved just a tad bit differently.,Let’s consider a parent component in our application:

See the following before ES6:

var object = {
   one: 1,
   two: 2,
   three: 3
}

A great role for destructuring assignment is within a React application. React uses a handy thing called props to send data between components. If that sentence means nothing to you, go learn about React! Props is an object, and is commonly passed down from a parent component to a child component.,Coding tutorials and news. The developer homepage gitconnected.com && skilled.dev,Suppose there is a parent component named <Peanuts/> and a child component called <Gang/>. To highlight the reduction in verbosity that destructuring assignment provides, both components will be class components. <Peanuts/> will be a container component, and <Gang/> will be a presentational component. <Peanuts/> will contain a list of Peanuts characters as an object which will be passed as props to <Gang/>, which will render the names of the characters.

In simple terms, the destructuring assignment is a way to customize how a value is accessed for use. It is a JavaScript expression that allows the extraction of values from an array or properties from an object and assigns the value or property as a distinct variable. Here’s an example of array destructuring:

let peanuts = ['Snoopy', 'Linus', 'Lucy']
let [snoopy, linus, lucy] = peanutsconsole.log(snoopy) //=> 'Snoopy'console.log(linus) //=> 'Linus'console.log(lucy) //=> 'Lucy'
