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.
