- The use of curly braces to surround blocks.
- The general insignificance of white space (spaces, tabs, new lines) except in very limited cases. Indentation is optional and is therefore a matter of style and preference, plus programs can be written on as few or as many lines as you want.
- The use of semicolons to end statements, expressions and other constructs. Semicolons become the delimiter that the new line character is in white-space-significant languages.
