    A utility object containing various type checking and validation functions. Provides methods to check if values are defined, null, functions, truthy/falsy, etc. Also includes derivative methods like not, all, and any for more complex validations.

    Type Declaration

    • defined: function

      • Checks if a value is defined (not undefined).

        Parameters

        • val: unknown

          The value to check

        • ..._args: unknown[]

        Returns val is Object

        True if the value is not undefined

    • exist: function

      • Checks if a value exists (is neither null nor undefined).

        Parameters

        • Optionalval: unknown

          The value to check

        • ..._args: unknown[]

        Returns val is Object

        True if the value is not null and not undefined

    • false: function

      • Checks if a value is strictly equal to false.

        Parameters

        • val: unknown

          The value to check

        • ..._args: unknown[]

        Returns boolean

        True if the value is exactly false

    • falsy: function

      • Checks if a value is falsy (converts to false in boolean context).

        Parameters

        • val: unknown

          The value to check

        • ..._args: unknown[]

        Returns boolean

        True if the value is falsy

    • function: function

      • Checks if a value is a function.

        Parameters

        • val: unknown

          The value to check

        • ..._args: unknown[]

        Returns val is Function

        True if the value is a function

    • null: function

      • Checks if a value is null.

        Parameters

        • val: unknown

          The value to check

        • ..._args: unknown[]

        Returns val is null

        True if the value is null

    • stringContaining: function

      • Checks if a string contains another string.

        Parameters

        • thisStr: string

          The string to search in

        • queryStr: string

          The string to search for

        Returns boolean

        True if thisStr contains queryStr

    • true: function

      • Checks if a value is strictly equal to true.

        Parameters

        • val: unknown

          The value to check

        • ..._args: unknown[]

        Returns boolean

        True if the value is exactly true

    • truly: function

      • Checks if a value is truthy (converts to true in boolean context).

        Parameters

        • val: unknown

          The value to check

        • ..._args: unknown[]

        Returns boolean

        True if the value is truthy

    • undefined: function

      • Checks if a value is undefined.

        Parameters

        • val: unknown
