Map function React

Does that help Kind of an obscure error, but the way you have it now, you'd be returning multiple nodes at the same level, so you need to wrap it with something.
Try this:
code :
const questionListItem = objectToArray.map(array => (
  <React.Fragment>
    <img src={imagePath(`./${array[0]}.png`)} alt="star" />
    array[1].map((question) => (
    <QuestionsListItem key={question.id} question={question} />)
  </React.Fragment>
));

ReactJS: React.render is not a function and React.createElement is not a function

like below fixes the issue First of all, since React v0.14, there is this new package called react-dom. It abstracts the "environment" that you will run React, and, in your case, is the browser.

should help you out I have a modal for login dialog that is triggered by clicking a non-react component.

componentWillReceiveProps(nextProps) {
  this.onLoginClick(nextProps);
}

onLoginClick (nextProps) {
    if (nextProps.login.length > this.props.login.length) {

I wish did fix the issue. Relevant docs are here:
https://reactjs.org/docs/react-without-es6.html
code :
class Greeting extends React.Component {
  render() {
    return <h1>Hello, {this.props.name}</h1>;
  }
}
var createReactClass = require('create-react-class');
var Greeting = createReactClass({
  render: function() {
    return <h1>Hello, {this.props.name}</h1>;
  }
});

fixed the issue. Will look into that further According to the Rules of Hooks:
code :
const SearchUserForm = () => {
  const client = useApolloClient();
  ...
    return (
      ...
      <button onClick={async (event) => {
        try {
          const { data } = client.query({
            query: searchUserQ,
            variables: { name: event.target.value },
          });
          // Do something with data, like set state
        catch (e) {
          // Handle errors
        }
      }} />
const SearchUserForm = () => {
  const [name, setName] = useState('')
  const { data, loading, error } = useQuery(searchUserQ, {
    variables: { name },       
  });
  ...
    return (
      ...
      <button onClick={async (event) => {
        setName(event.target.value)
        ...
      }} />
