How to use the webtorrent.WEBRTC_SUPPORT function in webtorrent

function init () {
  if (!WebTorrent.WEBRTC_SUPPORT) {
    util.error('This browser is unsupported. Please use a browser with WebRTC support.')
  }

  // For performance, create the client immediately
  getClient(function () {})

  // Seed via upload input element
  var upload = document.querySelector('input[name=upload]')
  if (upload) {
    uploadElement(upload, function (err, files) {
      if (err) return util.error(err)
      files = files.map(function (file) { return file.file })
      onFiles(files)
    })
  }

peerPublicKey: peerPublicKey,
      amount: incoming.destinationAmount
    })

    // Unchoke all of this peer's wires
    for (let wire of this.peerWires[peerPublicKey]) {
      wire.unchoke()
      wire.bidAmount = wire.bidAmount.times(this.bidIncreaseFactor)
      this._checkUnchokeWire(wire)
    }
  }
}

// Note that using module.exports instead of export const here is a hack
// to make this work with https://github.com/59naga/babel-plugin-add-module-exports
module.exports.WEBRTC_SUPPORT = WebTorrent.WEBRTC_SUPPORT

export const configureDragDrop = () =>
{
	if (WebTorrent.WEBRTC_SUPPORT)
	{
		dragDrop('body', async (files) => await shareFiles(files));
	}
};

render()
	{
		return (
			<div>
				<img src="{this.props.data.picture">
	
				<div>
