javascript - check to see if exactly two out of three booleans are true?

I need to test to see if exactly two out of three booleans are true.

Something like this:

if((a && b && !c) || (a && !b && c) || (!a && b && c)){
 //success
}

Is this the most direct way to go about this? Does anyone know of a shortcut / shorthand?

Answer

To check if exactly two are equal to true:

[a, b, c].filter(Boolean).length === 2;
