The byteLength accessor property of TypedArray instances returns the length (in bytes) of this typed array.

The byteOffset accessor property of TypedArray instances returns the offset (in bytes) of this typed array from the start of its ArrayBuffer or SharedArrayBuffer.

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 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 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 reduceRight() method of TypedArray instances applies a function against an accumulator and each value of the typed array (from right-to-left) to reduce it to a single value. This method has the same algorithm as Array.prototype.reduceRight().

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 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 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 Atomics.add() static method adds a given value at a given position in the array, and returns the old value at that position. This atomic operation guarantees that no other write happens until the modified value is written back.
