This book is aimed at readers who are interested in software development but have very little to no prior experience. The book doesn’t have any new information compared to what you can find online or in other books; it has two purposes: * It includes what I think is important for software development from a large variety of topics, saving the reader from the dilemma “what should I learn” * It collates relevant information from lots of sources in one book, saving the reader from going through several separate web sites and books It aims to contain an overview of almost everything that I think is important for software developers. It doesn’t contain everything; but it should contain enough for the reader to understand software development, and to be able to read about and understand any topic in further detail as needed. The book focuses on teaching the core principles around software development. It uses several technologies to this goal (e. g. C, Python, JavaScript, HTML, etc. ) but is not a book about the technologies themselves. The reader will learn the basics (or in some cases more) of various technologies along the way, but the focus is on building a foundation for software development.
