JavaScript 中是否有适当的“位”之类的东西？

Question

I know that there is a Boolean object in JavaScript, but I'm wondering if there is a way to access the metal, the raw single bit that lives at the heart of this Boolean object.

Answer 1

You can't access it, but you can assume true is 1 and false is 0 .

Answer 2

I don't know of any bit type in javascript. If you're worried about conserving space and need to store a lot of bits, you could probably use int s and Bitwise Operators in conjunction. You'd be manipulating the individual bits within each int (so 32 on most systems)
