According to me,
“Without JavaScript our site will be lifeless ”

JavaScript – Two new things
• Web workers
• Web socket
“2% or less disable JavaScript support”- Yahoo

47.
Web workers

48.
Web workers
• A web worker is a JavaScript that runs in the background,
independently of other scripts, without affecting the performance of
the page. You can continue to do whatever you want: clicking,
selecting things, etc., while the web worker runs in the background.

Web workers
• A web worker is a JavaScript that runs in the background,
independently of other scripts, without affecting the performance of
the page. You can continue to do whatever you want: clicking,
selecting things, etc., while the web worker runs in the background.
Demo : http://www.w3schools.com/html/html5_webworkers.asp and
Mozilla link
// in demo_workers.js
var i = 0;
onmessage = function (oEvent) {
timedCount();
postMessage("Hi " + oEvent.data);
};
function timedCount()
{
i = i + 1;
postMessage(i);
setTimeout("timedCount()",500);
}
if(typeof(w) == "undefined" && typeof(Worker) !== "undefined")
{
w = new Worker("demo_workers.js");
}
w.onmessage = function(event){
document.getElementById("result").innerHTML = event.data;
};
function stopWorker() { w.terminate(); }
w. postMessage(“Started”);

50.
Web socket
• WebSocket is a protocol providing full-duplex communications
channels over a single TCP connection.
• That makes it possible to open an interactive communication session
between the user's browser and a server.
Socket : http://docs.oracle.com/javase/tutorial/networking/sockets/definition.html

51.
Web socket - Example
if ("WebSocket" in window)
{
var ws = new WebSocket("ws://localhost:9998/echo");
ws.onopen = function()
{
ws.send("Message to send");
alert("Message is sent...");
};
ws.onmessage = function (evt)
{
var received_msg = evt.data;
alert("Message is received...");
};
ws.onclose = function() {alert("Connection is closed..."); };
}
