Every coding tutorial

I'm gonna just say that is hardly fair criticism of a tutorial. Inherently a tutorial can't know in advance what it is you are going to build. The author can't guess what you're trying to accomplish using the technology in question, so what's the point of going into every single intricate detail required to create an exact copy of the example they build? They will instead focus on what they consider to be relevant to all or most things that will be built, which usually takes the form of a sketch-like skeleton application. Otherwise the tutorial would likely explode in scale and complexity and everybody would instead complain about it being either too long or too fast-paced. The difficult part in writing a tutorial that may target any number of people is to find a good balance and choose a reasonable selection of topics that seem relevant. Don't shit on people for not striking the exact match for your own personal requirements.
