How to pass props one component to other component in react

Passing an array as props to a React functional component is quite straightforward. You simply include the array as a property when you use the component in your JSX code. Here's an example:

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

const ParentComponent = () => {
  // Define an array
  const data = [1, 2, 3, 4, 5];

  return (
      {/* Pass the array as a prop to ChildComponent */}
      <ChildComponent dataArray={data} />

export default ParentComponent;
Enter fullscreen mode Exit fullscreen mode

And here's the child component:

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

const ChildComponent = ({ dataArray }) => {
  // Now you can use `dataArray` inside the ChildComponent
  return (
      <h2>Data from Parent:</h2>
        {, index) => (
          <li key={index}>{item}</li>

export default ChildComponent;
Enter fullscreen mode Exit fullscreen mode

In this example:

  • ParentComponent defines an array called data.
  • It renders ChildComponent and passes data as a prop named dataArray.
  • ChildComponent receives dataArray as a parameter in its function component definition and uses it to render a list.

You can now access the array passed from the parent component (ParentComponent) within the child component (ChildComponent) using the prop name specified during its passing.
