A type that can be a Boolean, null, or undefined.
Object
An object with the can.new, can.getSchema, can.isMember symbols.
The strings "false" and "0" will be converted to false. Any
falsey values like "" will also be converted to false.
Use
Normally, MaybeBoolean is used as part of can-define or can-query-logic,
but it can be used directly too:
import MaybeBoolean from "can-data-types/maybe-boolean/maybe-boolean";
import canReflect from "can-reflect";
canReflect.new(MaybeBoolean, "true") //-> true
MaybeBoolean[Symbol.for("can.isMember")](true) //-> true
MaybeBoolean[Symbol.for("can.isMember")]("true") //-> false
MaybeBoolean[Symbol.for("can.isMember")](null) //-> true
