In my opinion, it is better to check the official documentation first and then other sources such as Stack Overflow or blog posts. While Stack Overflow has quite good quality control and provides indicators of whether an answer is worth considering, blog posts are of fluctuating quality. This becomes even worse when they apply SEO, because all the noise obscures other (perhaps better) solutions.
The official documentation of a product (usually) is the single source of truth, which is always usually up-to-date. Unfortunately, I am one of those developers that tend to take the easy road, especially because it is sufficient in most cases.
The least I should do is also confirm the solution I found with the official documentation. This year I want to do better. I will do my best to check the official documentation first or at least verify the results. This post should also serve as a reminder of that.
