Convert class component in React Javascript to Functional Component in React TypeScript

Question

I have been trying to integrate the JSONEditor into a React TypeScript application. The working sample of React JavaScript version is available at https://github.com/josdejong/jsoneditor/blob/master/examples/react_demo/src/JSONEditorDemo.js (and reproduced below). I have since ported the code into React TypeScript as under. Am I doing the right thing? Are any further improvements recommended?

React JavaScript version

import React, {Component} from 'react';
import JSONEditor from 'jsoneditor';
import 'jsoneditor/dist/jsoneditor.css';
import './JSONEditorDemo.css';

export default class JSONEditorDemo extends Component {
  componentDidMount () {
    const options = {
      mode: 'tree',
      onChangeJSON: this.props.onChangeJSON
    };

    this.jsoneditor = new JSONEditor(this.container, options);
    this.jsoneditor.set(this.props.json);
  }

  componentWillUnmount () {
    if (this.jsoneditor) {
      this.jsoneditor.destroy();
    }
  }

  componentDidUpdate() {
    this.jsoneditor.update(this.props.json);
  }

  render() {
    return (
        <div className="jsoneditor-react-container" ref={elem => this.container = elem} />
    );
  }
}

React TypeScript version

export const Editor = (props: IProps) => {
  
    const mode : JSONEditorMode = "tree";
    const elRef = React.useRef<HTMLDivElement | null>(null);
    const editorRef = React.useRef<JSONEditor | null>(null);
    
    const unmountEditor = () => {
        editorRef.current?.destroy();
    }

  React.useEffect(() => {
    //const container = document.getElementById("jsoneditor");
    const container = elRef.current;
    const options : JSONEditorOptions = {
        mode: mode,
        onChangeJSON: props.onChangeJSON,
    };

    if (container) { 
      const jsonEditor =  new JSONEditor(container, options);
      jsonEditor.set(props.json);
      editorRef.current = jsonEditor;
    }

    return unmountEditor;
  }, [props]);
  
    return <div id="jsoneditor" ref={elRef} className="jsoneditor-react-container" />;
  };
