FUNDAMENTAL

20 years ago, there were 2 distinct web page develop paradigms: Static & Dynamic. In the last 10 years there has been a paradigm shift, since Dynamic page rendering has become the standard. The paradigms are: Virtual DOM vs DOM. Web progammers know that there are 3 basic elements of programming web pages: HTML, JS and CSS... The Document Object Model (DOM) is a programming interface for web documents. It represents the page so that programs can change the document structure, style, and content. The DOM represents the document as nodes and objects; that way, programming languages can interact with the page... This approach enables the declarative API of React: You tell React what state you want the UI to be in, and it makes sure the DOM matches that state. This abstracts out the attribute manipulation, event handling, and manual DOM updating that you would otherwise have to use to build your app.
