how to play/pause video in React without external library?

Updated example for React Function Components:

import React, { useRef} from 'react'

function myComponent(props) {
  const vidRef = useRef(null);
  const handlePlayVideo = () => {
    vidRef.current.play();
  }
  return (
    <video ref={vidRef}>
      <source src={[YOUR_SOURCE]} type="video/mp4" />
    </video>
  )
}
