NotLuau✎

True when the value is `nil` or `false`, and false for everything else. Takes any value, so `not part` on an `Instance?` is the usual way to ask whether it is there. Note that 0 and an empty string are true in Luau. Brackets, in the Inspector, wraps the result in `( )`; precedence is handled either way.

Pending review

not

  • names its result — Result name in the Inspector is the local it binds, and a Declare Local reading that result makes a second one: see Variables and locals

Inputs

  • A:any= false

Outputs
