React.DOM Fails with undefined

Asked 1 years ago, Updated 1 years ago, 43 views

I want to learn the basics, so I want to move without JSX first, and when I use React.DOM.div, I get the following error:

build.js:20123 Uncaught TypeError: Cannot read property 'div' of undefined

const React=require('react');
// approximately

const HelloWorld=createReactClass({
  render: function() {
    return React.DOM.div({},
      'Hello World'+
      this.props.name);
  }
});
// approximately

"dependencies": {
  "create-react-class": "^15.6.3",
  "react": "^16.3.0",
  "react-dom": "^16.3.0"
}

You can run React alone and React+JSX on a directly specified CDN of the HTML script tag.
This is my own technique page.

React.DOM was announced to be decommissioned in React 15.x and was actually decommissioned in 16.0.

If you want to continue using the same API, the package react-dom-factories is available.
Currently, the official documentation introduces the use of React.createElement.
