Chapter 1. Introduction: Why ClojureScript?
This book aims to get you up and running with ClojureScript, a dialect of the Clojure programming language that compiles to JavaScript. To begin, this chapter will provide some motivation for why ClojureScript exists.
The Rise of Browser Applications
Web applications have come a long way from simple CGI scripts, but they have always been constrained by the stateless request-response model of HTTP. As the “pages” in a web application become more elaborate, the cost in time and bandwidth of reloading an entire page just to update a single piece of information becomes prohibitively high.
One of the first major uses of JavaScript on the web was to ameliorate the cost of small updates, but “web applications” remained primarily server applications for a long time, and for good reason. Deploying an application to a web server is much easier than distributing it to diverse client machines: the server is a controlled environment, with many more options for programming languages and frameworks. But by treating web browsers like dumb terminals, applications were severely limited by how quickly they could push updates to a client.
Recent years have witnessed the rise of what one might call browser applications. These applications typically still have server-side components, but a significant part of their logic runs client-side, in a web browser. The web browser acts like a virtual machine, executing JavaScript code to communicate with a server, render ...
