Novice challenge

Question

I've left some bugs in that code:

https://code.sololearn.com/WSUcOkZocp0p/?ref=app

find them and report them 😃

As I don't consider that to be too hard, the challenge is only valid for players up to lvl 10.
[EDIT] - level cap is now raised to 12.
[TIP] - there are two cases in which one of the methods will not act as it should.

Answer 1

98k!

Answer 2

@Amrit - stay tuned, if I don't get any answers, I'll increase the level cap 😃

Answer 3

@ $Vengat - despite the common opinion, I actually have a life and things to do in it 😂😂😂, will get there one of these days...

Answer 4

Congrats Nikolay 101k

Answer 5

OK. That seems to be too hard... Level cap is now 12.

Answer 6

@Jordan, not a bug - it returns undefined because the stack is empty 😃

Answer 7

JS is definitely not my best language but I've been looking at this code for the past 30 min and have found absolutely nothing wrong with neither the code or the output. It's a bit of a different way to handle things than I've ever done but it seems to work flawlessly. I guess I'll wait for somebody else to figure it out. Definitely a cool challenge though, thank you

Answer 8

@Christian - actually "return this" is always used in methods that do not return anything else to allow chaining

Answer 9

Nikolay go to level 17 first the whole sololearn's eyes are on you. Go for platinum level 17 by tomorrow

Answer 10

I will congratulate you here when you do:

Answer 11

Not sure exactly what the code is supposed to do but line 63 loops through 11(not 10) and leaves the last output as undef/null

not sure if that was a bug or just a way to show you're done

Answer 12

@Nikolay Nachev, thank you. I didn't know that before now, still learning Javascript.

Answer 13

well, seems we don't have a winner. The code is fixed now, comments above the bugs for those interested.

Answer 14

So I am not eligible.

And even if I am, I am bad at JS.

Answer 15

return this? Improper use of keyword and no property or method is specified to be returned.

Answer 16

What!? I am really bad at Javascript

Answer 17

@Joe 97k not 98k ✋

Answer 18

I would have never guessed. Seems to be more of a better way to setup the constructor than a bug that could actually cause problems though.

Answer 19

@Nikolay Nachev Congo in advance for lvl17.I think u will make it very soon
