What's the difference between these two line of code?

number = window.number|5;

number = window.number||5;

They both work as intended, but I am unsure the exact meaning of | vs || in these cases. Is there a chance that one would failed over the other?

The idea is to go like this when I am unsure if the page has loaded jQuery or not.

window.jQuery = window.jQuery|loadJquery();

They don't function the same - try `number = window.location | 5;`. Plus even if they did, why would you prefer a non-popular notation? To save a character? – nicholaswmin Apr 25 '17 at 01:07
Oh. I just figure out myself. number = 5|5; is a lot different than number = 5||5; – Noobit Apr 25 '17 at 01:14
no kidding relational vs bitwise who would've thought they where different – Dayan Moreno Leon Apr 25 '17 at 01:20
