can-data-types/maybe-boolean/maybe-boolean

  • Edit on GitHub

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

CanJS is part of DoneJS. Created and maintained by the core DoneJS team and Bitovi. Currently 5.33.3.
