Unary Operators

Operation	Symbol
Negate	!

• Negate will work on Number, String and Boolean.
  • !true -> false, and !false -> true
  • !1 -> false, and !0 -> false
  • !'' -> true and !'Hello' -> false
  Negate on objects and arrays

  You can also apply negate on objects on arrays, !{} gives false and ![] also gives false implying even empty objects and arrays are considered true internally and when negated give false.

Add, Concat	+
Subtract	-

Not equal	!=
Greater than	>
Greater than or equal	>=
Less than	<

Element in array or string	in

in operator on array of objects

The in operator can be used to check for a substring: 'Cad' in 'Ron Cadillac', and it can be used to check for an array element: 'coarse' in ['fine', 'medium', 'coarse']. However, the == operator is used behind-the-scenes to search arrays, so it should not be used with arrays of objects. The following expression returns false: {a: 'b'} in [{a: 'b'}].

Ternary Operator

• You can simply use <conditional> ? trueValue : falseValue anywhere in the transforms.
