what does '|' mean in JavaScript?

Question

I've seen a single | being used in code somewhere but I have no idea what it means. I know that || is 'or'.

I typed it in the console and these are my results:

1 | 0 // 1
0 | 1 // 1
1 | 2 // 3
2 | 4 // 6

Does | just add the two numbers? Or is there more?

You've discovered [bitwise operators](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators), huh? — tadman, May 05 '15 at 17:49

You're on the right way - the single pipe in JavaScript stands for a bitwise or. You can find the documentation here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators#.7c_%28Bitwise_OR%29
