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

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

Whoops! NONE of you up there got the answer.

1
and
1

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.
