Converting between strings and ArrayBuffers

Question

Is there a commonly accepted technique for efficiently converting JavaScript strings to ArrayBuffers and vice-versa? Specifically, I\'d like to be able to write the contents

Answer 1

if you used huge array example arr.length=1000000 you can this code to avoid stack callback problems

function ab2str(buf) {
var bufView = new Uint16Array(buf);
var unis =""
for (var i = 0; i < bufView.length; i++) {
    unis=unis+String.fromCharCode(bufView[i]);
}
return unis
}

reverse function mangini answer from top

function str2ab(str) {
    var buf = new ArrayBuffer(str.length*2); // 2 bytes for each char
    var bufView = new Uint16Array(buf);
    for (var i=0, strLen=str.length; i
