How to work with bytearray? about jsengine HOT 3 CLOSED

Looks like the seed is a array (list in Python) object, and its members' type is Number (int in Python). So, the code may like this:

byte_array = list(bytes.fromhex("93 14 2C 08"))  # both bytes and bytearray are OK
array = ctx1.call("calculateKey", byte_array)

from jsengine.

Why bytearrays? JavaScript has no this type, how does it work in JavaScript?

Here use string (ctx.eval) and supported types by json (ctx.call) to pass arguments to the backend engines.

Thank you for responce. Actually, I am not good in JS :)

Here is a part code of JS script:

function calculateKey(seed) {
    if (seed.length < 4) {
        throw "seed length must be at least 4";
    }

    var hiSeed = ((seed[0] << 8) + seed[1]) & 0xFFFFFFFF;
    var loSeed = ((seed[2] << 8) + seed[3]) & 0xFFFFFFFF;

and I still cant understand how to pass my byte arrar to that function :(
