Hello, Jeff! How come you stopped using the Windows Machine? lol
and btw SC looks great will watch it and follow it.
Hey Hassan – I still have my Windows setup. But I’ve become more comfortable with the Mac.
Oh i see! Well that is great
Dad just bought me the new 27″ iMac.. feels weird at the moment but getting used to it.
I think it culd be nice if you make some tasks we can do after we have learn what you have saying and showing us
hope you understand my english
Great stuff man, can’t wait for Chapter 3!
Your screencasts are digital awesome sauce.
Thanks Jeff.
This time am 1st to comment Yay
No you aren’t lol.
lol another fail
big time
Thank you Jeffrey Way for taking time to create such great tutorials.
I learned a lot from your tutorials, previously MySQLi prepared statements
and now Javascript.
Thanks! Glad to hear it.
What’s up with all the ads?
The cc 15 second ads at the beginning help to offset the expenditures.
You can always download a no-ads version from iTunes. 
great follow up!!!
This is great! Thanks as always Jeff.
Jen
Hello
great tut cant wait till next week and please dont use ur rap skills on the next episode Pwweeeeeeeees ;]
tnx
I hope there’s no newbie that’s going to try and make a script with JS on code canyon with what you’ve taught up till now, I remember when I graduated in a computer science degree I told myself I was probably ready to start making awesome plugin’s etc, boy was I wrong, competition is ferocious, what I could write in 50 lines, someone else wrote it in 25.
Just to say, there’s always some guy on top that will make you that awesome method in a recursive matter that will blow you away wondering how they come up with these things.
Anyways, looking forward to the other chapters, I’ve already learned JS(Made a few board games), but I dwelled into PHP and C++ so I lost a lot of my shine.

These Javascript tutorials are amazing, I really appreciate all your hard work. It really helps fill in the gaps that I have with the language.
Thanks alot!
Jeff, can I send you a PSD file?
Nice tutorial once again Jeff looking forward to getting a hold of the meaty JS next week ^^
You are GREAT!!!!! very helpful.
Wish these had been around about a month or two ago while I was eating books trying to learn this, hehe.
Very nice though, I’ll take these in when I need a refresh. They’re really great.
Thanks, man.
Looking forward to the next one(s).
Peace
Even I know bits & peaces, Thank you so much for the screencasts which is very useful to know all the basics.
Thanks, Jeff.
Thanks..!
They are great..!
Great series for a n00b like me!! Jeff, can you recommend a good Javascipt book as well???
Directed at beginners?
Self-promo time!
Beginning JavaScript is good. I’m not biased or anything
Absolutely. John – you can buy it here: http://www.amazon.com/gp/product/0470525932/
Beginning JavaScript is a fantastic resource if you’re just starting out John! I use it for reference pretty much daily
Good stuff as always. Can’t wait for some more elaborate stuff with Javascript. Thanks!
Jeff are you a coding God? I swear you know EVERYTHING. haha. thanks for this, I started watching it, and it suprised me how much I knew already (not alot) but hey, will continue to watch.
Big help to the community. Thank you.
Hey Alex – Not even close. I’m in awe of some of you guys.
Anyone know of a site that has a complete list of Javascript functions? I’ve searched, but to no avail.
Awesome tut, Jeff! You always seem to be on top of what we all need!
Great tutorial. Looking forward to watching next part soon.
Omg. Sites always start fine, but then come Ads and all goes to …
These JS tutorials are great… but somehow I have the sneaking suspicion that despite promising 10 CodeIgniter tutorials, Jeffery Way is gonna leave us short at 7
I really thought that raw javascript was harder then this. Looking forward to installment #3 next week.
Thanks for new chapter.
I think you should also go through useful functions like addEventListener.
Thanks. Good work. I waiting for other tutorial. Thank you so much
Hello Jeff, you are just awesome and I am a great fan of yours
I am waiting for a php tutorial of user management system with 4-5 user permission level which includes registration with email activataion, login etc. (Just like Joomla/WordPress)
We will be very glad to get it from you
Great series, i’m waiting for the next code igniter video
