call

Given a key and a set of arguments, call them when given a context. Primarily useful in composition.

Use a closure to call a stored key with stored arguments.

size
Get size of arrays, objects or strings.
Get type of value (array, object or string). Use length property for arrays. Use length or size value if available or number of keys for objects. Use size of a Blob object created from value for strings.
Split strings into array of characters with split('') and return its length.
