The “single var pattern” article is ignoring an alternative way to define variables using a single var that is closer to how JavaScript actually works than either of the variants the article discusses:

function() {
    // declarations
    var declare, your, using, single, statement, semicolon;

    // assignments separate from declarations
    declare = 'all';
    your = 'variables';
    using = 'a';
    single = 'var';
    statement = 'then';
    // Everything else.
}

Another reason for giving your functions names when you use them in event listeners is that it makes it easier to remove the event listener again.
