Chapter 04: Richardson Maturity Model

Since the turn of the millennium, the web has undergone rapid changes. Simple static websites began to be replaced by sophisticated web applications. At first, these were applications where the entire HTML code was generated on the server side. With the rise of JavaScript and technologies like AJAX, however, web applications emerged that could update content directly on the client side by manipulating the DOM (Document Object Model). This period, which began around the year 2000, is now often referred to as the era of Web 2.0.
