javascript - Node.js convert buffer to Int8Array -

in client side, converting typedarray blob , transmitting server, check if info correct, want compare first 5 values on client side , server side,

on client side:

var filereader = new filereader(); filereader.onload = function() { callback(new int8array(this.result)); }; filereader.readasarraybuffer(blob);

(from read first 5 values in callback fn)

but on server, found code convert blob buffer, , understanding, buffer , arraybuffer not same, var buffer1 = new buffer( blob, 'binary' );

does buffer have similar dataview of arraybuffer, how read first 5 values of buffer1 integers able in client side?
