The [Symbol.iterator]() method of Array instances implements the iterable protocol and allows arrays to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns an array iterator object that yields the value of each index in the array.

The length data property of an Array instance represents the number of elements in that array. The value is an unsigned, 32-bit integer that is always numerically greater than the highest index in the array.

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

The Array.fromAsync() static method creates a new, shallow-copied Array instance from an async iterable, iterable, or array-like object.

The entries() method of Array instances returns a new array iterator object that contains the key/value pairs for each index in the array.

The Temporal.Duration object represents a difference between two time points, which can be used in date/time arithmetic. It is fundamentally represented as a combination of years, months, weeks, days, hours, minutes, seconds, milliseconds, microseconds, and nanoseconds values.

The getTextInfo() method of Intl.Locale instances returns the ordering of characters indicated by either ltr (left-to-right) or by rtl (right-to-left) for this locale.

The Temporal.PlainYearMonth object represents the year and month of a calendar date, without a day or time zone; for example, an event on a calendar that happens during the whole month. It is fundamentally represented as an ISO 8601 calendar date, with year, month, and day fields, and an associated calendar system. The day is used to disambiguate the year-month in non-ISO calendar systems.

The Temporal.ZonedDateTime object represents a date and time with a time zone. It is fundamentally represented as a combination of an instant, a time zone, and a calendar system.

The <feGaussianBlur> SVG filter primitive blurs the input image by the amount specified in stdDeviation, which defines the bell-curve.
