How to Add Comments in JSX

To put comments inside JSX, you use the syntax {/* */} to wrap around the comment text.

You do actually need the curley brackets, and have to add it under the other elements for this to work. 

HTML

<div id="root"></div>

Scripts

<script type="text/babel">
const JSX = (
  <div> 
    <h1>This is a block of JSX</h1> 
    <p>Here's a subtitle</p>
    {/* Here is my Comment */}
  </div> 
);
ReactDOM.render(JSX, document.getElementById('root'))
</script>

Javascript

/*
const JSX = (
  <div> 
    <h1>This is a block of JSX</h1>

    {/* Here is my Comment */}
  </div>

In this case my anchor this week becomes driving almost 2hrs outside of Atlanta to one of my favorite hard core gyms in the world.. MetroFlex aka The Dungeon. The gym owners turn the heat way up so it becomes a fun sweat box and the gym members just watch from afar and leave me alone. I happily drive myself long distances to find MY ANCHOR. Our anchor allows us to have balance, focus and be as productive as possible. And if you're in the middle of a heavy set and your headphones start to fall off your head, like mine did here.. well.. f*ck the headphones. Let em break and fall. You can always get a new pair, but the iron ain't ever gonna lift itself.
