The course has been completely re-written, basically covering the same material but with many improvements (and in HD 1080P also)
More examples are included buiding apps using the React Context API including integrating HOC's and Context in the final module.
HOC's and Render Props are now in the final module of the course and the focus is more on React context. Also, the HOC and RPs discussions no longer have any dependency on previous code like they did before.
The first two modules are more focussed on passing props and functions through a component hierarchy then in the previous course. Much more detail is given on the ways to pass props and methods with an emphasis on the spread operator.
More effort is made to complete all coding demos without cutting and pasting code making it much easier to code along now. The complex reducer code has been removed and examples now have simpler reducers as examples.
A basic implementation of REST using NextJS API Routes has been added with methods for GET, INSERT, UPDATE and DELETE. GET returns all records and GET with a specific ID is not supported, though that would be simple to add.
The module for TailwindCSS has been removed and all course demos are not written in Bootstrap 4.5. There is no introductory session on Bootstrap like there was for Tailwind as it's assumed most people are famaliar with Bootstrap
The local REST server is now built with NextJS API Routes which was introduced in NextJS version 10 so there is no reason to launch json-server in this course now.
