I am not getting what or operator does with inters. I have following code
-1||4 // output -1
4||-1 //output 4
Does it converts integers in bytes and performs or operation.

1Only the number `0` is *falsey*... does that help? – deceze Apr 15 '16 at 14:22

It first checks wheter the number is truthy or falsey and returns the first truthy one. All numbers are truthy except for 0.
0 || 4; // 4
2 || 3; // 2 (picks the first one, because both true)
-3 || 0; // -3
0 || -2; // -2

No. The || operator is logical and, not bitwise and.

1It returns the first truthy value, or the last one unconditionally if all the preceding ones are falsey. So `0 || 0` returns `0` because the first value is falsey and the last value is zero. – RobG Apr 15 '16 at 14:29
