The Uint8Array typed array represents an array of 8-bit unsigned integers. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

The resolvedOptions() method of Intl.DurationFormat instances returns a new object with properties reflecting the locale and date and time formatting options computed during initialization of this Intl.DurationFormat object.

The resolvedOptions() method of Intl.Segmenter instances returns a new object with properties reflecting the locale and granularity options computed during the initialization of this Intl.Segmenter object.

The Number.parseInt() static method parses a string argument and returns an integer of the specified radix or base.

The Math.hypot() static method returns the square root of the sum of squares of its arguments. That is,

The Math.cosh() static method returns the hyperbolic cosine of a number. That is,

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 shift() method of Array instances removes the first element from an array and returns that removed element. This method changes the length of the array.

The Uint8Array() constructor creates Uint8Array objects. The contents are initialized to 0.

The toLocaleString() method of Number values returns a string with a language-sensitive representation of this number. In implementations with Intl.NumberFormat API support, this method simply calls Intl.NumberFormat.
