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 with() method of TypedArray instances is the copying version of using the bracket notation to change the value of a given index. It returns a new typed array with the element at the given index replaced with the given value. This method has the same algorithm as Array.prototype.with().

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 setFromBase64() method of Uint8Array instances populates this Uint8Array object with bytes from a base64-encoded string, returning an object indicating how many bytes were read and written.

The Uint8Array() constructor creates Uint8Array objects. The contents are initialized to 0 unless initialization data is explicitly provided.

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 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 length accessor property of TypedArray instances returns the length (in elements) of this typed array.
