What can you tell me about JSX?

When Facebook first released React to the world, they also introduced a new dialect of JavaScript called JSX that embeds raw HTML templates inside JavaScript code. JSX code by itself cannot be read by the browser; it must be transpiled into traditional JavaScript using tools like Babel and webpack. While many developers understandably have initial knee-jerk reactions against it, JSX (in tandem with ES2015) has become the defacto method of defining React components.

class MyComponent extends React.Component {
  render() {
    let props = this.props;  
    return (
      <div className="my-component">
      <a href={props.url}>{props.name}</a>
      </div>
    );
  }
}
