  1. there are definitely useful items, but i’m not sure if all them are applicable in certain elements of design; ie e-commerce.

  2. Noura, you missed a really important new framework that was released earlier this month, the JUNE Javascript Framework.

    There’s more about it and info by the developer over at that milw0rm posted.

    It’s probably the fastest, lightest JS framework to date and honestly should be listed, no questions asked! As always, great round up and awesome post!

  3. Has anyone use Jaxer in web development yet? It sounds cool ‘n all but i’m curious on how practical it is in relation to deployment, functionality, security, etc

  4. @ Noupe
    It’s one of the simplest frameworks i’ve used, and every inch of it is customizable to my liking, like my own personal library that does what I want/need it to do. It’s a wicked framework, light and what I would call a tool for hardcore JS coders that just want to code JavaScript. Sure it doesn’t include features like drag and drop and such, even though there are ways of implementing this, but it’s simply made for JS lovers, who just want to play with JS alone. Ah even though it might not be decent for huge sites, its perfect for small to middle sized online business/sites and easy enough to use by a novice too. Like i said, feel free to check out blog where the JUNE developer commented on the software and went into detail about it and so on. Thumbs up to Noupe for rocking as always!!

  5. Thanks Everyone for pointing out the Firebug being missed. Yesterday i added Firebug at the top of the Browser Tools list but i guess i didn’t include it by mistake when i was cleaning up the post in the Admin area.
    I added it again to the list and hopefully i am forgiven ;)

    Thanks @ BlackHat Fish. I didn’t hear about June before nor tried it. Could you give us your experience with it?

  6. I very much rely on Web Developer extension for Firefox & Firebug and would happily recommend it to any other web developer and designer.

    These make my life much more easier.

  7. One _very_ important tool is missing: JSLint by Douglas Crockford:
    It doesn’t make coding faster, but it forces you to write a clean, relatively safe code that is compatible with different browsers, so you spend less time finding bugs… and it WILL hurt your feelings ;)

  8. I used Clean ajax and I do not use it anymore.
    Because it hangs up Firefox when a get or a post call
    hangs because of the server.
    And the development of Clean ajax was stopped.
    I use prototype now yuicompressed and gzipped
    so it is 23 kbyte now.
    And oncomplete function is much more easier in prototype.

  9. there are definitely useful items, but i’m not sure if all them are applicable in certain elements of design; ie e-commerce.

  10. DO NOT, I repeat DO NOT use Snippely, as it does not have a backup option. So if you want to reinstall Windows and save your snippets, YOU CAN’T.

  11. You should also try

    jsFiddle – great for client side prototyping
    Akshell – free hosting of more complex projects, together with the ability to run server side code

  12. I happen to be commenting to let you know of the outstanding discovery our daughter undergone using the blog. She even learned a wide variety of pieces, with the inclusion of what it is like to have an incredible giving nature to let the others effortlessly comprehend selected extremely tough subject matter. You undoubtedly surpassed my expectations. Many thanks for providing these warm and friendly, healthy, explanatory as well as fun guidance on your topic to Evelyn.
