Not function
This function can be used to reverse the truthiness of a value.

not() | Reverses the truthiness of a value. |
not
The not function reverses the truthiness of a value. It is functionally identical to !, the NOT operator.
API DEFINITION
not(any) -> bool
RETURN not("I speak the truth");
A value is not truthy if it is NONE, NULL, false, empty, or has a value of 0. As such, all the following return true.
RETURN [
not(""),
not(false),
not([]),
not({}),
not(0)
];
Similarly, the function can be used twice to determine whether a value is truthy or not. As each item in the example below is truthy, calling not() twice will return the value true for each.
RETURN [
not(not("I have value")),
not(not(true)),
not(not(["value!"])),
not(not({i_have: "value"})),
not(not(100))
];
Doubling the ! operator is functionally identical to the above and is a more commonly seen pattern.
RETURN [
!!"I have value",
!!true,
!!["value!"],
!!{i_have: "value"},
!!100
];
