Apr 11, 2012 · While this is rather easy with actual pointers and memcpy, I couldn't find any straightforward way to do it in Javascript. Right now, this is how I copy my ArrayBuffers: function copy (buffer) { var bytes = new Uint8Array (buffer); var output = new ArrayBuffer (buffer.byteLength); var outputBytes = new Uint8Array (output); for (var i = 0; i < bytes.length; …

The ArrayBuffer.transfer() method allows you to grow and detach ArrayBuffer objects. The ability to grow an ArrayBuffer without copying has the advantage of being much faster for large buffers (similar to realloc). The ability to detach an ArrayBuffergives the developer explicit control over when the underlying memory is released. This avoids havin...

DataView. There is a flexible untyped view over the ArrayBuffer, known as DataView. With it, you can access the data on any offset in any format.

Starting with ECMAScript 2015, ArrayBuffer constructors require to be constructed with a new operator. Calling an ArrayBuffer constructor as a function without new, will throw a TypeError from now on. JavaScript Copy Code var dv = ArrayBuffer ( 10 ); // TypeError: calling a builtin ArrayBuffer constructor // without new is forbidden JavaScript
