    Very basic javascript question! Newbie alert!

    So, I'm teaching myself javascript basics and had a question:

    When I write something like

    Code:
    var $fullName = $firstName + ' ' + $lastName;
    Why do i have to have 2 '+' operators instead of just one? I thought you write it like

    Code:
    var $fullName = $firstName + ' ' $lastName;
    Thank you.

    Hey skunker,

    You write it with two pluses because you are concatenating three strings: $firstName, a space and $lastName.

    PPK has a good explanation of this: http://www.quirksmode.org/js/strings.html#conc
