In the function below, how come you have to precede "this.tick()" with "() =>" ?
componentDidMount() {
this.intervalID = setInterval( () => this.tick(), 100)
}

231,141 PointsThat creates an anonymous function. Without seeing the context, I'd guess it might be to control the binding of "this".
But try it this way and see if it works:
componentDidMount() {
this.intervalID = setInterval(this.tick, 100)
}
