imod5 says:

One thing I don’t understand regarding continue and break in while loops, is if they ignore anything that follows between the parentheses in the while loop, why is the document.write function then executed?

Outdoor Activities says:

Excellent! I am at the very beginning of teaching my granddaughter to code. This is an outstanding introduction to not only Javascript but to coding in general. Kids get bored easily but I don’t think she will be bored by this!

Narayan Sampath says:

if you know any programming language just please skip this video all it has is just what is variable, how you name them, types of variables and basic stuff

Frank Moss says:

Actually, I thought it was great! I am learning Java, so I appreciate the opportunity to go through quickly just to see what is different between the two. Thanks!

Russell Scott says:

Hey Derek do you have any tutorials on creating Browser extensions ?

Ali Alavi says:

Hey Derek,
I like it so much. Going fast though everything is what I was looking for. It gave an overall understanding of JavaScript and if I need details of anything, I can refer to the reference documents for that. Keep making videos like this 🙂

Trip Foundation says:

thanks it was very nice and has helped me alot

Nelly Tadi says:

Sincerely, I love you so much for all your effort. So far i have learnt a lot because of your tutorials. God bless you

Jeff Dunn says:

This style is great for me. There is another channel on the Internet called “Conversational Korean” that has a similar ‘rapid deployment’ of information. I really appreciate it, because, I do get bored with a slower presentation.
Please keep it up, and I will keep up my subscription for sure!

Srinivas Siddarth says:

Hi, Derek, you are the fastest teacher but still i can grasp every bit of it, in one go. By the way did anyone else tell you that you sound like Howard Stern? You have a great voice. Man you should try to have your own talk show. Thanks a lot for all your wonderful videos.They are Very very very educating and informative.!

Hari Pandey says:

Great Job!…. Man you made me hover through the whole coding thing in just one go… awesome !

Paul Zak says:

This was a great quick overview. Helpful if you are coming from another scripting language.

Paul Foster England says:

I love your tutorials man, but the fact that you sound like Reverend Lovejoy from The Simpsons is very distracting and amusing 🙂

Asif Hakim says:

can some one tell me what the name of application that he used is called or tell me the link thnx:)

Ali Alavi says:

Btw, it would be good if you recommend an editor for JavaScript and/or show how you make JSs within HTMLs.

Mulagura says:

It’s interesting listening to your uncertainty about cramming so much into one video given what’s come since.

hiUpeople723 says:

– undefined

Eric Johnson says:

Your videos are excellent. Thank you!

Trish Ladd says:

It might be worth noting that toFixed causes a number to become a string, I did notice that you referred to it as a string several times and used typeOf to show that it was a string – but this might get missed by a person new to JS, which is why I put this comment in, though it probably won’t get seen by many.

So if you do use toFixed and then add it to a number you get a concatenated value, rather than an actual total. Made this mistake early in my JS career.

Pavel Minetskiy says:

“completely crazy”))) I like it. Thank you for your lesson!!
