Before I start working on a project, I spend a couple of minutes to read and understand the logic of the current code base related to the change. By doing this, it naturally reminds me about the language syntax, the framework, the project convention, and the team's best practice. If you do it regularly, you will feel it more natural. Most of the modern languages' projects are easy to identified the scope of changes. Don't pay too much attention to the languages syntax, but rather to the logic.
