The way we build web and mobile device applications is changing fundamentally. What this change is - in a nutshell - is application code moving from the server to the client. The server being big computers sitting in a data centre somewhere and the client being a modern day browser. To explain this further, let’s call the old way of building web sites as web 2.0 and the new way as web 3.0.
In the past, when web 2.0 was all the rage, web sites were built with a lot of server side code written languages such as c#, php or java. This code ran on various web server application platforms such as Microsoft ASP.Net. The code ran on the server and spat out HTML which was rendered on a browser and allowed the user to interact with the application. There was probably was a bit of JavaScript but none of which was essential to the application doing what it needed to do.
