The <feFuncR> SVG filter primitive defines the transfer function for the red component of the input graphic of its parent <feComponentTransfer> element.

The <cursor> SVG element can be used to define a platform-independent custom cursor. A recommended approach for defining a platform-independent custom cursor is to create a PNG image and define a cursor element that references the PNG image and identifies the exact position within the image which is the pointer position (i.e., the hot spot).

An Iterator object is an object that conforms to the iterator protocol by providing a next() method that returns an iterator result object. All built-in iterators inherit from the Iterator class. The Iterator class provides a [Symbol.iterator]() method that returns the iterator object itself, making the iterator also iterable. It also provides some helper methods for working with iterators.

This chapter introduces collections of data which are indexed by a key; Map and Set objects contain elements which are iterable in the order of insertion.
