Checking for `null` or `undefined` in JavaScript

Say I want to check if a value v is either null or undefined in JavaScript. I might use this conditional:

if (!v) { ... } // 🙅‍♀️ wrong!

	class Sliceable:
	def __init__(self, iterable):
	self.it = iterable

	def __getitem__(self, index):
	if isinstance(index, int):
	return self.it[int]

	start = 0 if index.start is None else index.start
	stop = inf if index.stop is None else index.stop

	export const enum WordBreakProperty {
	/* 0 */ Other,
	/* 1 */ LF,
	/* 2 */ Newline,
	/* 3 */ CR,
	/* 4 */ WSegSpace,
	/* 5 */ Double_Quote,
	/* 6 */ Single_Quote,
	/* 7 */ MidNum,
	/* 8 */ MidNumLet,
