Hello, welcome to therichpost.com. In this post, I will tell you, How to render an array of objects in React?Reactjs is a Javascript Library to build user interface. Now I am also learning Reactjs these day because of my passion to learn new things.

In this post, we will render an array data.  We will use map is used to convert an array with items of type “string” to an array of React.DOM.li elements.

 

Here is working and tested code and I have added this in index.js file:
import React from 'react';
import ReactDOM from 'react-dom';

class Hello extends React.Component{
  constructor()
  {
    super();
    //declare custom data array of object
    this.state = {
      names:['ajay', 'alisha', 'jas']
    }
  }
  render()
  {
    return (
      <ul>
      {
        //map array data
        this.state.names.map(function(name){
            return <li key={name}>{name}</li>
        })
      }
      </ul>
    )
  }
}

ReactDOM.render(<Hello />, document.getElementById('root'));
