@ -26,6 +26,7 @@ This means:
- 4 spaces indentation
- `camelCase`, **even for constants or enums**. Why? Because `SCREAMING_CASE` is ugly, annoying to type and does not achieve anything useful. Constants are *less* dangerous than variables, not more.
- No underscores for anything. (Yes, I know `Bindings` violates this principle, but that's for legacy reasons and really should be cleaned up some day)
- Do not use braceless `if/else` statements. `if(x) statement else statement2` should **never** be done. In very specific situations, having braceless if-statements on one line is allowed: `if(cond) return;` would be valid.
