const file = e.files[0];
var reader = new FileReader();
reader.readAsArrayBuffer(file.rawFile);
reader.onload = function () {
     var strBytes = new Uint8Array(reader.result).join();
     var byte=???;

• 2 .join() converts the Uint8Array to a string. If you don’t want a string, don’t call .join(). – Ry- ♦ Commented Jul 17, 2017 at 6:24

When creating a Uint8Array, the data is stored as bytes, which is exactly what you are looking for here.

What you've done when using .join() is to create them as strings.

Just remove the .join and you will have an array of bytes:

var strBytes = new Uint8Array(reader.result);
