The good news is that the JavaScript language has also made some progress in order to satisfy this, and other needs that have come about. One such addition to JavaScript in recent years is a new data type: typed arrays. In general, typed arrays offer a structure similar to the array type already in JavaScript. However, these new arrays are much more efficient, and were designed with binary data in mind.
