I have three arrays:

• arr1=[14,16,1] — where I am selecting


• arr2=[14] — where I am comparing my selection from arr1


• arr3=[] — where I am pushing the value.

How will I be able to check if my selection does not exist in arr2?

For example I selected 14 from arr1, since it is already existing in arr2, the button will be disabled and should not be pushed in arr3.
