Not all operating systems, code editors/IDE’s treat code indentation the same way. I prefer to use spaces for alignment. Seriously. else if (isThing) otherFn(); // Do awesome stuff function foo() { Examples of incorrect code for this rule: (I’ll admit this is an edge case that’s kinda tangential to the main discussion). Check the Wiki for some real-world examples of projects using EditorConfig files.. Where are these files stored? Things to remember in your TABS vs SPACES discussion: ADAPT if you work with a specific practices, coding language/framework, or editor (such as VIM) there may be additional pros and cons. “2: Saved space on disk” As a bonus, tab width can be changed unlike spaces and this allows a developer who hates, say wide indentation to visualize a narrower indentation while coding. Also, many editors get de-denting wrong so you can’t even fall back to using Shift+Tab.
