Example 1: ternary operator react

render () {
  return (
    

      { //Check if message failed
        (this.state.message === 'failed')
          ? 
 Something went wrong 
 
          : 
 Everything in the world is fine 
 
      }
    
  );
}

Example 2: conditional rendering react

import React, { Component } from 'react';

// @params [] * denotes optional param (we will need to use conditional rendering for some of these)
// [type](Bulma CSS class): Hero type, focuses on the base styling
// size(Bulma CSS Class): The size of the hero, small, medium, large, etc...
// heading: The main heading
// [subheading]: The subheading if desired
// [alignment](Bulma CSS Class): Aligns the content horizontally

// This Simple HeroComponent is bases upon the following
// https://bulma.io/documentation/layout/hero/ 

export class HeroComponent extends Component
{
	render() {
		return (
          	// The following ternary simply applies a class if it has been specified
			

				

                  	// Again, another ternary applying a class... blah blah blah....
					

						
{this.props.heading}
						// So, to answer the question...
						// The following is one way to do conditional rendering, probably the simplest and cleanest
						// If this.props.subheading exists, render 

						{this.props.subheading && 
{this.props.subheading}
}
					
				
			
		)
	}
