In-Depth Promise Tutorial with Running Code Examples

'Promise' is very 'docile'. Once the code has been correctly configured, Promise becomes one of those "plug & forget" tools. The tutorial is organized into sections. Each section deals with one aspect of the correct configuration of Promise. Each section is associated with a js file with the code needed for the (exact) understanding of the concepts exposed. Starting from section 3, All the possible configurations of the 'Promise' are covered in all their details. (This tutorial should be studied with the browser in debug mode. In that way, the 'click' on the buttons leads directly to the correct point in the code.)
