Variables

isNullOrUndefined

Returns true whether the payload is null or undefined

Functions

f getType	Returns the object type of the given payload
f isAnyObject	Returns whether the payload is an any kind of object (including special classes or objects with different prototypes)
f isArray	Returns whether the payload is an array
f isBlob	Returns whether the payload is a Blob
f isBoolean	Returns whether the payload is a boolean
f isDate	Returns whether the payload is a Date, and that the date is valid
f isEmptyArray	Returns whether the payload is a an empty array
f isEmptyObject	Returns whether the payload is a an empty object (excluding special classes or objects with other prototypes)
f isEmptyString	Returns whether the payload is ''
f isError	Returns whether the payload is an Error
f isFile	Returns whether the payload is a File
f isFullArray	Returns whether the payload is a an array with at least 1 item
f isFullObject	Returns whether the payload is a an empty object (excluding special classes or objects with other prototypes)
f isFullString	Returns whether the payload is a string, BUT returns false for ''
f isFunction	Returns whether the payload is a function (regular or async)
f isInstanceOf	Checks if a value is an instance of a class or a class name. Useful when you want to check if a value is an instance of a class that may not be defined in the current scope. For example, if you want to check if a value is an `OffscreenCanvas` instance, you might not want to do the song and dance of using `typeof OffscreenCanvas !== 'undefined'` and then shimming `OffscreenCanvas` if the types aren't around.
f isMap	Returns whether the payload is a Map
f isNaNValue	Returns whether the payload is literally the value `NaN` (it's `NaN` and also a `number`)
f isNegativeNumber	Returns whether the payload is a negative number (but not 0)
f isNull	Returns whether the payload is null
f isNumber	Returns whether the payload is a number (but not NaN)
f isObject	Returns whether the payload is a plain JavaScript object (excluding special classes or objects with other prototypes)
f isObjectLike	Returns whether the payload is an object like a type passed in < >
f isOneOf	A factory function that creates a function to check if the payload is one of the given types.
f isPlainObject	Returns whether the payload is a plain JavaScript object (excluding special classes or objects with other prototypes)
f isPositiveNumber	Returns whether the payload is a positive number (but not 0)
f isPrimitive	Returns whether the payload is a primitive type (eg. Boolean \| Null \| Undefined \| Number \| String \| Symbol)
f isPromise	Returns whether the payload is a Promise
f isRegExp	Returns whether the payload is a regular expression (RegExp)
f isSet	Returns whether the payload is a Set
f isString	Returns whether the payload is a string
f isSymbol	Returns whether the payload is a Symbol
f isType	Does a generic check to check that the given payload is of a given type. In cases like Number, it will return true for NaN as NaN is a Number (thanks javascript!); It will, however, differentiate between object and null
f isUndefined	Returns whether the payload is undefined
f isWeakMap	Returns whether the payload is a WeakMap
f isWeakSet	Returns whether the payload is a WeakSet
