    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:

    Code:
    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.
