function isNil(value)

We instead have function isNullOrUndefined(value) ... instead, but it does the same thing.

It's especially lame since you can't just do if (!value) ... since that includes 0 (but not [] or {}, which Python considers falsey). It's remarkably inconsistent...

basically every language under the sun has NaN

Yup, but you can use NotNan in Rust, just like your NonNull example.

And yeah, it's weird that JavaScript doesn't have an integer type, everything is just floating point all the way down. I actually did some bitwise logic with JavaScript (wrote a tar implementation for the web), and you get into weird situations where you need to >>> 0 in order to get an unsigned 32-bit integer (e.g. (1 << 31) >>> 0). Those hacks really shouldn't be necessary...

Because it's floating point it also causes some REALLY strange bounds on integers. The maximum sized int you can safely store in JS is a 53 bit integer. That caused us all kinds of headaches when we tried to serialize a 64 bit integer and it started producing garbage results for very large values.
