List Rendering in ReactJS

List rendering in ReactJS refers to the ability to render a list of items dynamically based on data provided by an array or other iterable data source.

Here is an example of how to use list rendering in ReactJS:

  1. Start by defining an array of data to render:
    const items = ['item 1', 'item 2', 'item 3'];
  2. In your component’s render method, map over the array of data and return a new array of React elements:
    render() {
      return (
          { => (
            <li key={item}>{item}</li>

    Note that each element in the array needs a unique key prop. This is important for React to efficiently update the DOM when changes are made to the list.

  3. The resulting output will be a list of items:
      <li>item 1</li>
      <li>item 2</li>
      <li>item 3</li>

List rendering is a powerful feature of React that allows you to easily render dynamic lists of items. It’s also commonly used when working with APIs and dynamically generating content from external data sources.
