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...Yup, but you can use
NotNanin Rust, just like yourNonNullexample.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
>>> 0in 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.
