You can combine Promises logically into new Promises. That makes it trivially easy to write code that says, “When all of these things have happened, do this other thing.”

composedPromise = $.when(anAsyncFunction(), anotherAsyncFunction());

The Deferred object exposes a then method which allows the developer to handle both the fulfillment and error states.   

Example:

$.ajax({

url: 'http://search.twitter.com/search.json',

dataType: 'jsonp',

data: { q: '#IE10', rpp: 100 }

})

transition:  [ <transition-property> ||               <transition-duration> ||               <transition-timing-function> ||               <transition-delay> ]

Example:

transition: width 2s, height 2s, transform 2s;

• linear
• ease
• ease-in
• ease-out
• ease-in-out
• cubic-bezier(n,n,n,n)

cubic-bezier(n,n,n,n) - Define your own values in the cubic-bezier function. Possible values are numeric values from 0 to 1

text-shadow: h-shadow v-shadow blur color;

• translate()
• rotate()
• scale()
• skew()
• matrix()

navigator.geolocation.getCurrentPosition(function (pos) {
    alert("yallo... your determined position is: " +
    pos.coords.longitude + " / " + pos.coords.latitude);
});

Web Workers allow you to do things like fire up long-running scripts to handle computationally intensive tasks, but without blocking the UI or other scripts to handle user interactions.

var worker = new Worker('task.js');

worker.postMessage(); // Start the worker.

When postMessage() is called from the main page, our worker handles that message by defining an onmessage handler for the message event. The message payload (in this case 'Hello World') is accessible in Event.data.

There are two ways to stop a worker: by calling worker.terminate() from the main page or by calling self.close() inside of the worker itself.

FormData gives you a way to create HTML forms on-the-fly using JavaScript, and then submit them using XMLHttpRequest.send().  

Example: 

var formData = new FormData(); formData.append("part_num", "123ABC");  formData.append("part_price", 7.95); formData.append("part_image", somefile)   var xhr =

new XMLHttpRequest(); xhr.open("POST", "http://some.url/");   xhr.send(formData);

The API allows you to do things like set a custom error, check whether an element is valid, and determine the reason that an element is invalid.

Example:

if (input.value != document.getElementById('email_addr').value) {

input.setCustomValidity('The two email addresses must match.');  

}

else {    

// input is valid -- reset the error message    

input.setCustomValidity('');  

}
