    Great video, but I noticed in your video you said a stack is first in first out by mistake, stacks are last in first out (lifo).

  • @Ben: I concur Wink

    thanks for this video :)
    i'm just wondering if we can use jQuery instead of JavaScript in windows 8 store app?

  • Gerardo Melendrezpayini Gerardo Melendrez

    Excellent video. Thank you guys.

  • @Moumen: Hi, check out the free eBook from MS Press. Kraig has some notes on why vanilla jQuery can't run as Windows 8 Store App. It is related to local app context and web app context and their different permissions related to DOM code injections as jQuery does.

    How can I find the videoes of day 2 please?

    PS:@Joki, thank you for your helpful link.

  • Hi

    you have question 

     

    var x = 200; function someFunc(y) { function innerFunction() { return x + y; } } x = someFunc(x);

    and when i choose null it show me that its incorrect but why?

    you declare sumeFunc which have declaration of subfunction but this function is never called, so result of someFunc should be null.

    or maybe i miss some thing?

  • MagedMaged

    first of all,
    thanks for the wonderful series
    and all the effort you put in these great video course.

    for the self assessment on this video i got a question about what functions that you can use with an array
    choices [ push, concat, add, join, map ]
    according to a slide in your video all apply except add ..i answered by checking all except it but it says a wrong answer
    does "add" apply can be used as an array function ?

    sorry but currently i don't have visual studio on the computer i am on now so i can't test it

    Thanks

  • Big Smile good one again!

  • NeilNeil

    @Belkin => the reason the answer to the question

    var x = 200; function someFunc(y) { function innerFunction() { return x + y; } } x = someFunc(x);

    is not null and is 400 is because the value of x (200) is being passed into the someFunc as the argument y so as far as someFunc is concerned both x and y now equal 200 so it simply returns 200 + 200.

    I hope this helps :)

    Thanks,

    Neil.

    Great work guys! I really enjoy the way you explain contents! Nice.

  • a great video. I would like to point out a small correction, at 11.58 Jereme mentions the stack as First In First Out which is wrong. stack is Last In First Out. for example when you push three items and when you pop it, the third item goes out. so it is LIFO

  • Excellent material. I hope you continue to post more.

    In module 4b you are spelling cauliflower wrong. You show it as cauliflovd but you spell it "cauliflower".

  • I realized even though I know little English. Congratulations you.

  • Overview of the core capabilities of JavaScript video (module 04a) mismatching with question. Code for ops method and video 15.46 mismatching with last semicolon.

     

     

  • In module 4 question: Correct method of calling the function to multiply the two numbers in module 4 video 04a (15.47) showing semicolon after curly brace  i'e }; but in question code for ops method that semicolon  not found.  Expressionless 

    So what is the correct method of calling the function to multiply the two numbers ?? which option is correct? I clicked first option but still confused for self correction.

    Regards,

    Debashis
