šŸš«šŸ˜© An array of react refs

Apparently you can't store React refs in an array. For some reason they get wiped out, so if you need to store a collection of refs, you have to do something like this (forgive me lord, for I hath sinned):

import React from 'react'

const collection = ["label 1", "label 2"]

class SinFactory extends React.Component {
  constructor(props) {
    super(props)
    this.ref0 = React.createRef()
    this.ref1 = React.createRef()
  }

  render() {
    return (
      <div>
        {collection.map((label, i) => {
          return <div key={label} 
            ref={this[`ref${i}`]}>{label}
          </div>
        })}
      </div>
    )
  }
}

It's truly filthy, but it works.
