The slice() method of SharedArrayBuffer instances returns a new SharedArrayBuffer whose contents are a copy of this SharedArrayBuffer's bytes from start, inclusive, up to end, exclusive. If either start or end is negative, it refers to an index from the end of the array, as opposed to from the beginning.

The toReversed() method of TypedArray instances is the copying counterpart of the reverse() method. It returns a new typed array with the elements in reversed order. This method has the same algorithm as Array.prototype.toReversed().

The Uint16Array() constructor creates Uint16Array objects. The contents are initialized to 0.

The buffer accessor property of DataView instances returns the ArrayBuffer or SharedArrayBuffer referenced by this view at construction time.

The setBigUint64() method of DataView instances takes a BigInt and stores it as a 64-bit unsigned integer in the 8 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The DataView() constructor creates DataView objects.

The has() method of WeakSet instances returns a boolean indicating whether an object exists in this WeakSet or not.

The delete() method of WeakSet instances removes the specified element from this WeakSet.

The toArray() method of Iterator instances creates a new Array instance populated with the elements yielded from the iterator.

The filter() method of Iterator instances returns a new iterator helper that yields only those elements of the iterator for which the provided callback function returns true.
