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 Boolean object represents a truth value: true or false.

The TypedArray.of() static method creates a new typed array from a variable number of arguments. This method is nearly the same as Array.of().

The sort() method of TypedArray instances sorts the elements of a typed array in place and returns the reference to the same typed array, now sorted. This method has the same algorithm as Array.prototype.sort(), except that it sorts the values numerically instead of as strings by default.

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 toLocaleString() method of TypedArray instances returns a string representing the elements of the typed array. The elements are converted to strings using their toLocaleString methods and these strings are separated by a locale-specific string (such as a comma ","). This method has the same algorithm as Array.prototype.toLocaleString().

The filter() method of TypedArray instances creates a copy of a portion of a given typed array, filtered down to just the elements from the given typed array that pass the test implemented by the provided function. This method has the same algorithm as Array.prototype.filter().

The map() method of TypedArray instances creates a new typed array populated with the results of calling a provided function on every element in the calling typed array. This method has the same algorithm as Array.prototype.map().

The Math.asin() static method returns the inverse sine (in radians) of a number. That is,

The toPrecision() method of Number values returns a string representing this number to the specified precision.
