I love this gist, because it shows a simple example for a higher order component.

I am not sure if this is the perfect place, but maybe people are interested to read a more elaborated gentle introduction to higher order components when they come across this gist looking for HOC examples.

is this the first ever written HOC ?

Wow, the React community really flubbed on terminology here. In this gist, the component utilizing what we call the HoC is called the HoC, whereas the thing we call the HoC is called an "Enhancer." This makes way more sense, as a "HoC," as it is known today, is not itself a component at all. Sad!!

Not quite see the difference between HoC and old decorator pattern. I would say HoC is a nice react implementation of decorator pattern.

Your constructor needs super(props) as the first line
