How to use OR condition in a JavaScript IF statement?

Question

I understand in jQuery (or JavaScript for that matter) if you want to link conditions together you can say:

if (A && B) { do something }

But how do I implement an OR uch as:

if (A OR B) { do something }

Answer 1

if (A || B) { do something }

Answer 2

Use the || operator.

Answer 3

simply use doublepipe that is ||

Answer 4

|| is the or operator.

if(A || B){ do something }

Answer 5

Worth noting that || will also return true if BOTH A and B are true.

In javascript, if you're looking for A or B but not both, you'll need to do something similar to:

if( (A && !B) || (B && !A) ) { ... }
