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.

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?

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

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.

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

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.
