Join Alex Banks for an in-depth discussion in this video Creating a display component, part of Building a Polling App with Socket IO and React.js.
- The neat thing about React is that…we can create reusable helper components…that allow us to hide any complex implementation…in an easy-to-use component.…In this lesson, we're going to create a display component…that we can wrap around a group of children…and display them based upon a condition…that we send to the component as a property.…So to get started, I'm going to go over…to my components folder and expand that,…and then go into my parts folder,…and I will add this file here.…I'm going to right-click over the parts folder…and select New File,…and then I will instantly save this file as Display.js.…
Now, consider our traditional if-else statement.…If a condition is true, then we can return…"The condition is true."…Otherwise, we can return…"The condition is false."…So this is our classic if-else statement.…Now, in React, it gets kind of tricky…to write if-else statements like this with JSX.…So we have a great helper,…the shorthand if-else statement.…Instead of returning "The condition is true"…or returning "The condition is false,…
