Asynchronous vs synchronous in javascript

you often see the terms asynchronous and synchronous in javascript. there is significant difference between the 2 and it affects the way you code. When executing something synchronously, you wait for it to finish before moving on. When executinge something asynchronously, you move on to the next task before it finishes.

google map geocoding is asynchronous for example, so you need to pass a callback method to execute upon completion of the request
