The toString() method of Symbol values returns a string representing this symbol value.

The Symbol.keyFor() static method retrieves a shared symbol key from the global symbol registry for the given symbol.

The prototype property of GeneratorFunction.prototype is shared by all generator functions. Its value is Generator.prototype. Each generator function created with the function* syntax or the GeneratorFunction() constructor also has its own prototype property, whose prototype is GeneratorFunction.prototype.prototype. When the generator function is called, its prototype property becomes the prototype of the returned generator object.

The every() method of Iterator instances is similar to Array.prototype.every(): it tests whether all elements produced by the iterator pass the test implemented by the provided function. It returns a boolean value.

The [Symbol.matchAll]() method of RegExp instances specifies how String.prototype.matchAll should behave.

The deref() method of WeakRef instances returns this WeakRef's target value, or undefined if the target value has been garbage-collected.
