React Js How To Pass Properties Object To Child Component

React JS is a powerful library used to build user interfaces with ease. One common task you may encounter while working with React is passing properties from a parent component to a child component. This process is essential for creating reusable and modular code. In this article, we will go through the steps on how to pass a properties object to a child component in React JS.

To pass a properties object to a child component, we first need to define the properties in the parent component and then access these properties in the child component. Let's start by creating a simple example to demonstrate this concept.

In our parent component, let's create an object named "user" with properties such as name, age, and city:

Jsx

import React from 'react';
import ChildComponent from './ChildComponent';

const ParentComponent = () => {
  const user = {
    name: 'John Doe',
    age: 30,
    city: 'New York'
  };

  return (
    <div>
      <h1>User Information</h1>
      
    </div>
  );
};

export default ParentComponent;

In the parent component, we defined an object named "user" with name, age, and city properties. We then passed this object as a property to the ChildComponent by using the syntax `user={user}`.

Next, let's create the ChildComponent to access and display the properties passed from the parent component:

Jsx

import React from 'react';

const ChildComponent = (props) =&gt; {
  const { user } = props;

  return (
    <div>
      <p>Name: {user.name}</p>
      <p>Age: {user.age}</p>
      <p>City: {user.city}</p>
    </div>
  );
};

export default ChildComponent;

In the ChildComponent, we accessed the properties passed from the parent component using the props parameter. By destructuring `const { user } = props;`, we can easily access the user object in the child component and display its properties using the curly braces syntax `{user.propertyName}`.

Now, when the ParentComponent is rendered, the ChildComponent will receive the user object as a property and display the user's information.

In conclusion, passing properties objects from a parent component to a child component in React JS is a fundamental concept that allows you to create dynamic and reusable components. By following the example provided in this article, you can easily implement this feature in your React applications. Experiment with different properties and components to further enhance your understanding of passing properties in React.
