Is there a way to shorten the following
if (a === b || a === c || a === d)
down to something like
if (a === b || c || d)
The issue with the last section is it will test if a === b, or if c is true, or if d is true.

it depends on the values of the variables. – Nina Scholz Mar 15 '16 at 15:15

@Quentin If that is the only way to go about doing this, then it would use more code to create the object than just leaving it how I originally had it. – ZomoXYZ Mar 15 '16 at 15:18

1`[a, b, c, d, e, f, ...].some(function (a, i, aa) { return i && aa[0] === a; })` works for any length. – Nina Scholz Mar 15 '16 at 15:28
