Typo in lecture 2 of week 1

[giorgi-tsu]

There is a typo in subsection called Line 1 is a valid Julia expression

At the end of page 4 in the note there is written the following paragraph:

"Finally, let’s note that some parts of line 1 would by themselves be valid code, namely the name and the value. A valid expression can be part some larger valid expression."

Actually, the name (mystringexample1) only from line 1 (mystringexample1 = "Hello, world") is not a valid expression hence is not a valid code. Why? because if you type on the name without the equal sign at the REPL and hit enter you receive:

ERROR: UndefVarError: mystringexample1 not defined.

P.S. This is not the case in video as in the video instructor mentions that only string alone can be a valid code which is true.

I belive that if the name was already defined then entering just the name could be a valid line of code. However I do see a typo in the line, "can be part some larger valid expression.". I think it should be "can be part of some larger expression.".
