A function is a piece of code that sits dormant until it is referenced or called upon to do its “function”. Instead of having to type the code every time you want something done, you can simply call the function multiple times to get the same effect.
function hello() {
var test = 'this is a test from hello function';
alert(test);
}

AJAX (Asynchronous JavaScript and XML), or Ajax, is a group of inter-related web development techniques used for creating interactive web applications. A primary characteristic is the increased responsiveness and interactivity of web pages achieved by exchanging small amounts of data with the server “behind the scenes” so that entire web pages do not have to be reloaded each time there is a need to fetch data from the server.
