This document is the official manual for Haxe 4. As such, it is not a beginner's tutorial and does not teach programming. However, the topics are roughly designed to be read in order and there are references to topics "previously seen" and topics "yet to come". In some cases, an earlier section makes use of the information of a later section if it simplifies the explanation. These references are linked accordingly and it should generally not be a problem to read ahead on other topics.
We use a lot of Haxe source code to illustrate theoretical matters in a practical way. These code examples are often complete programs that come with a main function and can be compiled as-is. However, sometimes only the most relevant parts are shown. Source code looks like this:

Furthermore, we define a set of terms in this document. Predominantly, this is done when introducing a new type or when a term is specific to Haxe. To avoid clutter, we do not define every new aspect we introduce, e.g. what a class is. A definition looks like this:
In a few places, this document has trivia-boxes. These include background information such as why certain decisions were made during Haxe's development or how a particular feature has changed as Haxe has developed. This information is generally not essential reading and can be skipped if desired:
