NULL_KEY

Description

Constant: string NULL_KEY = "00000000-0000-0000-0000-000000000000";

The string constant NULL_KEY has the value "00000000-0000-0000-0000-000000000000"

While technically a string constant, it is only useful as a key.

Despite fitting the syntax criteria to be a valid key, when fed to a Conditional as a key it executes as false.

In most applications NULL_KEY isn't needed; an empty string will suffice.

Like any string constants longer then 3 characters and used in multiple places in the code, they should be store in a global variable. The result will be a considerable memory savings.
