Learning JavaScript Functions, Part 2

Posted by on Oct 8, 2012 in Blog, podcast, Video | 14 comments

The second in a several-part series on JavaScript functions, taking you from first principles to advanced concepts. In this video, Eric describes how function names are just like other JavaScript variables: they’re variable names pointing to function values.

    Soon!

  • Joe Hanson

    Loved it, can’t wait :)

  • Brian Hudgins

    Beautiful. Perfect. And taught in a way that no book – even a Head First book – can convey quite as well. I agree with the others – more, please, and thank you.

    That was very well explained, can’t wait to see the rest of the series.

    Great video. I have had the HTML 5 book for a few months. I just started reading it a couple of days ago. I really like the book.

    I just asked for a copy of Michael Morrison’s Headfirst JavaScript as a birthday present

    You just assigned the nameless function to a variable.

    You just blew my mind :D

    You know, I can’t find this series on YouTube.

      Hi Leke, we aren’t posting these on YouTube, just wickedlysmart.com! Thanks.

    Not to be a stickler here, and I could be totally wrong, but at 3:29 you say,”In this case we have an argument of ‘weight’ we pass the parameter of ’15′ ..”

    Did you mean the other way around? A -parameter- of ‘weight’ we pass the -argument- of ’15′ ?
    I’m using page 120 of HF HTML5 for reference.

    Great video by the way.

      Yes, it’s backwards! Which is a little embarrassing, given that we made that point in HF HTML5! ;-)

        I got so nervous after I posted that. I checked the errata at the o’reily forums and didn’t find anything there and then consulted some of my javascript colleagues; all confirmed what you replied.

        No worries at all! The community absolves you, as long as you hire me ;)

        I’ll gladly make the coffee and ‘gopher’ this and that.

      You are painfully correct. We’ve been meaning to go edit this but haven’t gotten to it. Given our lecture on page 120 it’s even more embarassing ;(
