I find Youtube's watch history helpful, having that across everything I watched on my device would be even better.

But this is wrong in at least two ways:

> Additionally, if the hash contains duplicate keys, swapping the keys and values may not have the desired effect.

You can't have duplicate keys in a hash.

You can partially apply the function where you know the parameter; i.e. assign onDelete to: this.handleDelete.bind(this, i)

68M per second == 68K per millisecond
