$$boolean

Evaluates input to boolean using the Truthy logic

Usage

{ 
  "$$boolean": /* input */,
  "style": "JAVA" /* or JS */
}

"$$boolean([style]):{input}"

note

Concrete values in the usage example are default values.

Strings evaluation depends on style argument:

• By default, value must be "true" for true.
• Unless style is set to JS, then any non-empty value is true. Arrays and objects of size 0 returns false.

Returns

boolean
