Create MCQA for Array.sort() method

kirandash commented 1 year ago

Please create an MCQA to be added as question number 29.

The multiple choice question should be on the topic .sort() method of an array. The difficulty level should be "Medium/Hard"

Tasks:

[ ] add your code to 029 folder under code
[ ] add your question to 29 in README.md file
[ ] create a video explanation and upload on YouTube (optional)

Explanation:

arr.sort(): sorts alphabetically when arr is of strings
This modifies the original array
To do numeric sort: use comparison method in callback function inside sort
if no callback fn is given then it will sort the unicode string value

Sample interview question for inspiration

What will be the output of ["bgwebagency", 1, 2, 3, 4, undefined, 11, 9, 1000, "apple", undefined].sort()?
- ans: [1, 1000, 11, 2, 3, 4, 9, 'apple', 'bgwebagency', undefined, undefined]
- all undefined values are moved to the end
How will you sort an object literal?
- ans: by using a callback function
How will you sort a numeric array?
Sort all values of array in descending order.

Hi @murat114, I just noticed that there is already a PR for this issue at https://github.com/bgwebagency/who-wants-to-be-a-javascriptaire/pull/20 by another user although this issue was not assigned to them.

Is it ok if you pick any issue other than #14 and #7 since there are PRs for these two issues.

But if you have already started working on it then I will not use their PRs. Since you are assigned to this task

Hi @kirandash, I have already started the work and wanted to finish it by next week at the latest. But if there is no other way I could start the task Create MCQA for Date() class #16. That would not be a problem for me.

Thanks a lot for understanding! Since there's another PR for this task already, I don't want their effort to be wasted. If you have not finished working on this, I think it will be better if you can work on #16. But please comment there first so that I can assign you.
