Please:
1. Answer before you try it out,
2. Give technical explanation for your answer

The first answer is 1
A do while loop will do at least one loop irrespective of the condition, that is even if the condition isn't met, the code would still run for the first time.
So x is increased by 1 for the first time x=0+1=1;
On the second iteration,the loop is broken because the condition is considered and 1 is not less than 0


The second answer is 9.
The loop is going to iterate 9 times so if 0 increases by 1 nine times , it will be 9

The first answer is one as you rightly said but for the second question I think the answer is 10 not 9 because the loop will run from i=0 to i=9 so k=10 before the loop terminates

lol... Yh...

0-9 is 10 counts

Lol... This isn't logic at all

This question is like breaking toothpick.. And iroko tree still dey forest

Breaking the toothpick will give you the courage to face the iroko. Have high expectations.

Whoops! NONE of you up there got the answer.

The first one can't be 1, as long as X<0, console.log might yield 0 or fail.
The second code should yield 9, since index i and variable k both starts with 0 and increments by 1 to i<10.

On a second look, I think K = 0. Because K is outside the for{} loop.

The first one will display 1 because the code contained within the two braces (do and while) will excecute at least once

The second one will display 0 because its a post increment operator(the increment is done after the variable is read) so it will keep on assigning 0 to k.

Question 1 would give an error

Because curly braces shouldn't just come after while(k<0)

NOT TRUE. You can have curly braces there, although I don't usually see it used that way.

What language is that.... On c++ its not so
