Statement is a piece of code that is telling that something needs to be done. That could be to call some function, to assign value to something, etc.
The important thing to know at this stage is, that every statement in Rittle must be completed with a ‘;’ character. A statement ends where the logic meaning of something ends, and something else starts from there.
If a source line contains only one statement, then the closing ‘;’ character is optional and can be omitted.
