    If you’re Googling for a decent JavaScript reference on a given topic, include the “mdc” keyword in your query and your first results will be from the Mozilla Developer Center. I don’t carry any offline references or books with me. I always use the “mdc” keyword trick to directly get to what I’m looking for. For example:

    Google: javascript array sort mdc
    (in most cases you may omit “javascript”)

    Update: Mozilla Developer Center has been renamed to Mozilla Developer Network. The “mdc” keyword trick still works, but soon enough we may have to start using “mdn” instead.
