There are many code styles. Is indented with tabs or with spaces? How many spaces? –
A uniform code style facilitates the work in the team,
but this is made more difficult by incorrect default settings in the editor.
The EditorConfig offers help when dealing with different code styles.
Personally I like to look at the commit history of different projects. Often I find that the commit messages provide only little information about the actual changes in the code.
Good commit messages help
in the review process, when creating changelogs, to be capable of tracking the changes to the source code made by other software developers. This means that good commit messages show whether you are a team player or not.
