how to write createElement in jsx react code example

Example 1: react.createElement

//Below I use the React.createElement() function to create a virtual DOM
//representation of a <li> element node containing a text node of one (a.k.a.,
//React text) and an id of li1.

var reactNodeLi = React.createElement('li', {id:'li1'}, 'one');

Example 2: javascript in jsx

const name = 'Josh Perez';
const element = <h1>Hello, {name}</h1>;
//notice the use of {...} to jump from jsx to javascript.
ReactDOM.render(
  element,
  document.getElementById('root')
);
