Port80: Practical JavaScripting

This talk will focus on practical advice to improve your JavaScript. We’ll look at JavaScript optimisation, tools that do a lot of the work for you, ways to make your code more robust, manageable and how to test it. We’ll also look at the future of JavaScript, what we can expect in the near future and how these enhancements can help us write even better code.

  1. Practical JavaScripting

  2. Me! University of Bath Computer Science Student Software Developer at

    Kainos Blogger at javascriptplayground.com Talker on upfrontpodcast.com Twitterer @Jack_Franklin
  3. None
  4. Free Stuff 5 Copies of "Beginning jQuery" to get rid

    of Tweet #port80jquery and I'll pick some randomly.
  5. What we're not going to talk about Do NOT let

    me do my Welsh accent we won't discuss England letting Wales beat us at rugby
  6. The Agenda Web Sites vs Web Apps Sensible JavaScript Writing

    Workflow & Tooling Don't get caught in the storm Book giveaway (Easy) Questions and (hopefully some) Answers
  7. Web Sites vs Web Apps is there a difference?

  8. None
  9. I don't think there is any difference and that's a

    good thing
  10. we're all building sites people visit, do something and leave

    stop trying to differentiate
  11. differentiating web sites vs web apps is no good to

    anyone
  12. a lot of people ignore new JS tools, methods or

    approaches because those are just for "web apps"
  13. don't be so quick to discredit your code

  14. Writing sensible JavaScript

  15. I get to see a lot of JavaScript and people

    write some weird stuff
  16. None
  17. None
  18. None
  19. People put a lot of thought into CSS (OOCSS, SMACSS,

    etc) (and this is a good thing) But does the same happen with the JavaScript?
  20. Too often people treat JavaScript like a black box of

    magic and throw everything into one file
  21. Too often it's an after thought let's quickly add some

    jQuery to animate that button
  22. "weeks of coding can save hours of planning"

  23. Let's talk about jQuery

  24. ditching jQuery has the time come?

  25. jQuery 2 drops IE6, 7, 8 jQuery 1.X supports them

  26. jQuery isn't going anywhere fast and the file size isn't

    that big...
  27. Organise your code multiple JS files, modular approaches

  28. organising your code is really simple lots of files and

    a bunch of script tags
  29. or you can go further AMD approaches like Matt talked

    about look at RequireJS
  30. learn how JavaScript works

  31. bits of JavaScript will catch you out and even jQuery

    can't save you from that
  32. the better you know JavaScript, the better you know jQuery

    Would you write SCSS without knowing CSS?
  33. regular JS isn't that bad. Make an effort to improve

    your JS knowledge you can still use jQuery. Knowing JS means you'll use it better and appreciate it more learn.jquery.com
  34. Tooling

  35. don't dismiss tools out of hand but don't go crazy

    and use them all, either
  36. The JS ecosystem has evolved a gazillionbillion* times over *

    needs attribution
  37. you're not a real developer if you don't use the

    command line* * loljk.
  38. Grunt! does everything. gruntjs.com

  39. Testing Minifying & Building Validating Templating

  40. you might not think your site needs {insert library here}

  41. there are a lot of times when you think your

    solution is too basic to require any additional libraries / tools but any chance you get to make your life easier is worth taking
  42. not getting caught in the storm

  43. don't worry about using the newest of the new tools

    if you do this, you'll never get any work done
  44. sure, when something new pops up, give it a quick

    look people (like me) will blog about them
  45. find a workflow, set of tools and some of your

    favourite libraries that work for you stick with them
  46. revisit every few months to see if something new has

    popped up
  47. spot small things that take up too much time and

    solve them
  48. Something takes you 5 minutes to do You spend an

    hour setting up that tool which makes that 5 minute thing a 1 minute thing everytime you do it you now save 4 minutes do that thing 15 times = your hour back
  49. take time to improve and perfect your workflow mundane but

    important tasks should be effortless
  50. the moment a mundane task takes considerable effort, you wont

    do it
  51. build for small wins lots of small wins > one

    big win
  52. we're all building web applications just some are a bit

    more complex than others
  53. develop accordingly, but don't treat your JS like this black

    box of magic
  54. and go make awesome

  55. Books! I'm going to give 3 out now randomly via

    Twitter Which means I'll have 2 left. At the after party, come and find me and tell me your best joke. If I like it, you can have a copy. If I don't, you get to buy me a drink.* * not really. Twitter Draw
