Separators
Characters, which separate tokens are the line-feed and carriage-return character and also:
( ) [ ] { } ;
Later on, the line-feed character and carriage-return character are simply refered to as newline characters.
Also line-comments are treated the same as newline characters. They are started with // and range till the next newline character. Therefore
myFunction()
is the same as
myFunction() // this is a function call
Operators are also separators.
