How to return an array of bytes in JavaScript?
The easiest way to return an array of bytes in JavaScript is to use the Uint8Array object. Uint8Array objects are easy to create and use. To create an array of bytes, you need to pass in the size in bytes. For example, to create an array of 8 bytes you would use the following code: var myBytes = new Uint8Array(8); With the array created, you can now fill it with any values and use it as a return value. For example, to return an array of 8 bytes containing the numbers 2, 4, 6, 8, 10, 12, 14, and 16, you would use the following code: var myBytes = new Uint8Array([2, 4, 6, 8, 10, 12, 14, 16]); return myBytes;
