+## Explain AJAX
+
+## Demonstrate jQuery AJAX
+
+```html
+<!DOCTYPE html>
+<html>
+	<head>
+		<title></title>
+		<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
+	</head>
+	<body>
+		hi
+		<script type="text/javascript">
+			$(function(){
+				$.ajax({
+					url:'http://www.omdbapi.com/',
+					method: "GET",
+					data: { s: "star wars" },
+					success: function(data, status, jqXHR){
+						console.log(data);
+					},
+					error: function(jqXHR, status, error){
+						console.log('bad');
+					}
+				});
+			});
+		</script>
+	</body>
+</html>
+```
+
+## Explain promises
+
+```html
+<!DOCTYPE html>
+<html>
+	<head>
+		<title></title>
+		<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
+	</head>
+	<body>
+		<script type="text/javascript">
+			$(function(){
+				var promise = $.ajax({
+					url:'http://www.omdbapi.com/',
+					method: "GET",
+					data: { s: "star wars" }
+				});
+				promise.done(function(data){
+					console.log(data);
+				});
+				promise.fail(function(data){
+					console.log('fail!');
+				});
+				promise.always(function(data){
+					console.log('always!');
+				});
+			});
+		</script>
+	</body>
+</html>
+```
+
+more succinct with extra done:
+
+```html
+<!DOCTYPE html>
+<html>
+	<head>
+		<title></title>
+		<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
+	</head>
+	<body>
+		<script type="text/javascript">
+			$(function(){
+				$.ajax({
+					url:'http://www.omdbapi.com/',
+					method: "GET",
+					data: { s: "star wars" }
+				})
+				.done(function(data){
+					console.log(data);
+				}, function(data){
+					console.log('another done');
+				})
+				.fail(function(data){
+					console.log('fail!');
+				})
+				.always(function(data){
+					console.log('always!');
+				});
+			});
+		</script>
+	</body>
+</html>
+```
+
+custom deferred and promise objects:
+
+```html
+<!DOCTYPE html>
+<html>
+	<head>
+		<title></title>
+		<script type="text/javascript" src="jquery-1.11.3.min.js"></script>
+	</head>
+	<body>
+		<script type="text/javascript">
+			var deferred = $.Deferred();
+			var promise = deferred.promise();
+			setTimeout(function(){
+				deferred.resolve("first promise");
+			}, 1000);
+
+			var deferred2 = $.Deferred();
+			var promise2 = deferred2.promise();
+			setTimeout(function(){
+				deferred2.reject("second promise");
+			}, 5000);
+
+			promise.fail(function(value) {
+				console.log('fail first: ' + value);
+			}).always(function(value){
+				console.log('always first: ' + value);
+			}).done(function(value){
+				console.log('done first: ' + value);
+			});
+
+			$.when(promise, promise2)
+			.done(function(value1, value2){
+				console.log('done both: ' + value1 + ", " + value2);
+			}, function(value1, value2){
+				console.log('2nd done both: ' + value1 + ", " + value2);
+			})
+			.then(function(value1, value2){
+				console.log('then both success: ' + value1 + ", " + value2);
+			}, function(value1, value2){
+				console.log('then both fail: ' + value1 + ", " + value2);
+			})
+		</script>
+	</body>
+</html>
+```
+
+## Explain Cross Site AJAX
+
+```javascript
+$.ajax({
+	url: 'https://status.github.com/api/status.json',
+	success: function(data) { console.log(data) },
+	error: function(jqXHR, status, errorThrown){ console.log(status); }
+});
+```
+
+look at console
+
+## Explain JSONP
+
+```html
+<!-- Request sent via a script tag -->
+<script src="https://status.github.com/api/status.json?callback=apiStatus"></script>
+<!-- Data received as an execution of the predefined function. -->
+<script> function apiStatus(data) { console.log(data.status); } </script>
+```
+
+## Explain CORS
+
+1. http://www.omdbapi.com/?s=pirates&r=json
+1. `Access-Control-Allow-Origin:*`
