28,558 PointsQuotes are used to create Strings (text). When you are referencing something that is not a string like a variable, number or any other type of value you don't use them. On the second line name refers to the variable declared on the first line.
Since name contains a string you can combine it with other strings and do anything else you would with an actual string, but a variable is never surrounded by quotes when referenced, regardless of what it contains.
If you did add quotes to the second line then name would be treated as pure text so the result would be "Hello name" instead of "Hello Dave".

28,904 PointsThe name is a variable so it does not need any quotation marks around it. the "Hello " is a string so it needs quotation marks.
