 <p>To achieve maximum flexibility and efficiency, JavaScript typed arrays split the implementation into <strong>buffers</strong> and <strong>views</strong>. A buffer (implemented by the {{jsxref("ArrayBuffer")}} object) is an object representing a chunk of data; it has no format to speak of, and offers no mechanism for accessing its contents. In order to access the memory contained in a buffer, you need to use a view. A view provides a context — that is, a data type, starting offset, and number of elements — that turns the data into an actual typed array.</p>
