The documentation shows good and bad examples in two large blocks, but this means that finding the right way to do things takes longer than necessary. I'd suggest this format:
❌ if (Object.is(foo, NaN)) {}
✅if (Object.is(foo, Number.NaN)) {}❌ isNan(1)
✅ Number.isNaN(1)
⚠️ These are not equivalent, you might want this instead:
✅ if (typeof numberOrIdk !== number || Number.isNaN(numberOrIdk)) {
