how to render child components in react.js recursively

by

Here’s an alternative in ES6:

import React, { Component, PropTypes } from 'react'

export default class Comments extends Component {

  render() {

    const { children } = this.props

    return (
      <div className="comments">
        {children.map(comment =>
          <div key={comment.id} className="comment">
            <span>{comment.content}</span>
            {comment.children && <Comments children={comment.children}/>}
          </div>
        )}
      </div>
    )

  }

}

Comments.propTypes = {
  children: PropTypes.array.isRequired
}

And is some other component:

<Comments children={post.comments}/>
