The indexOf() method of TypedArray instances returns the first index at which a given element can be found in the typed array, or -1 if it is not present. This method has the same algorithm as Array.prototype.indexOf().

The propertyIsEnumerable() method of Object instances returns a boolean indicating whether the specified property is this object's enumerable own property.

The findIndex() method of TypedArray instances returns the index of the first element in a typed array that satisfies the provided testing function. If no elements satisfy the testing function, -1 is returned. This method has the same algorithm as Array.prototype.findIndex().

The setInt32() method of DataView instances takes a number and stores it as a 32-bit signed integer in the 4 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 getFloat32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit floating point number. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

The setFloat32() method of DataView instances takes a number and stores it as a 32-bit floating point number in the 4 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 AggregateError() constructor creates AggregateError objects.

The Symbol.asyncIterator static data property represents the well-known symbol @@asyncIterator. The async iterable protocol looks up this symbol for the method that returns the async iterator for an object. In order for an object to be async iterable, it must have an @@asyncIterator key.

The setInt16() method of DataView instances takes a number and stores it as a 16-bit signed integer in the 2 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 getUint32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit unsigned integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.
