The ByteArray class provides methods and properties to optimize reading, writing, and working with binary data.
How to use byte arrays tutorial.
I'm looking for a very similar API as the one linked.
I'm looking for a class the browser provides not hack or workaround. The linked question does not provide the answer. If it does please provide a link to the documentation.
Some one linked to another question but that did not answer my question.
Update: Someone off list pointed me to this class:
https://gist.github.com/sunetos/275610#file-bytearray-js
It has most or all of the read methods but none of the write methods and it's not native to the browser.
回答1:
Modern browsers support Uint8Array, one of JavaScript's TypedArray classes.
var data = new Uint8Array(8);
var data = new Uint8Array([0x10, 0x12]);
It does not have built-in methods for encoding/decoding Unicode strings. See Converting between strings and ArrayBuffers for examples of how to do that.

The answer is yes, here are the relevant docs since you just wanted this...
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays
The linked docs for each type in the above docs show the methods available on each type. IE: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Int8Array
