Short example does not include infinity and NaN

[skoehler]

Please enhance the example in README.md so that it also shows +/-infinity and NaN values. I'd like to know how these are represented and whether it's compatible with python.

[jordanbtucker]

Infinity and NaN are used just like any other numeric value. Just like in ES5, they are case sensitive. You can put a + or - directly in front of them.

They are both compatible with Python. In Python 2, Infinity and NaN are represented by float('inf') and float('nan'). In Python 3, they are represented by math.inf and math.nan.

[skoehler]

Sure, I already looked it up in the sources. Just make life easier for lazy people like me. Also, you want to show off all your features in your small example, no?
