As a general case I recommend always terminating each statement with a semi-colon. Then it is explicit to the interpreter and other coders (and "other coders" includes "you six months later when you've forgotten most of what you did today") that you intended this to be the end of the statement and the next line to be the start of a new one.

Only ever leave the semi-colon out at the end of a line when you are explicitly using a multi-line statement to make your code more readable.

This makes your intent unambiguous in both cases; to the interpreter/compiler, to other tools, and to other humans.
