javascript - Converting byte[] to ArrayBuffer in Nashorn -

how convert array of bytes arraybuffer in nashorn? trying insert binary data pure javascript environment (i.e., doesn't have access java.from or java.to) , create instance out array of bytes.

looks going wrong way. made more sense convert uint8array since i'm sending in is array of bytes.

i created following function:

function bytetouint8array(bytearray) {     var uint8array = new uint8array(bytearray.length);     for(var = 0; < uint8array.length; i++) {         uint8array[i] = bytearray[i];     }      return uint8array; } 

this convert array of bytes (so bytearray of type byte[]) uint8array.
