The [@@iterator]() method of Iterator instances implements the iterable protocol and allows built-in iterators to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns the value of this, which is the iterator object itself.

The take() method of Iterator instances returns a new iterator helper that yields the given number of elements in this iterator and then terminates.

The toString() method of Boolean values returns a string representing the specified boolean value.

The clear() method of Set instances removes all elements from this set.

The [@@iterator]() method of Segments instances implements the iterable protocol and allows Segments objects to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns a segments iterator object that yields data about each segment.

The add() method of Set instances inserts a new element with a specified value in to this set, if there isn't an element with the same value already in this set

The symmetricDifference() method of Set instances takes a set and returns a new set containing elements which are in either this set or the given set, but not in both.

The <feMerge> SVG element allows filter effects to be applied concurrently instead of sequentially. This is achieved by other filters storing their output via the result attribute and then accessing it in a <feMergeNode> child.

The GeneratorFunction object provides methods for generator functions. In JavaScript, every generator function is actually a GeneratorFunction object.

The bitwise XOR (^) operator returns a number or BigInt whose binary representation has a 1 in each bit position for which the corresponding bits of either but not both operands are 1.
