JS Time's Up! Challenge Question

Question

I'm having some trouble understanding the while loop, specifically with the JS Time's Up! challenge question:

Write a program-timer, that will take the count of seconds as input and output to the console all the seconds until timer stops.

Sample Input
4

Sample Output
4
3
2
1
0

My code:
function main() {
var seconds = parseInt(readLine(), 10)
// Your code here
while(seconds>=0);
document.write(seconds + '<br />');
seconds--;

}

What am I missing?

Answer 1

Cameron Please remove the semicolon on this line.

while(seconds >=0); {

Your while while loop should just look like this...

while(seconds>=0) {
console.log(seconds);
seconds--;
}

Answer 2

It's just a syntax issue. Your while loop needs curly braces.

while(seconds>=0) {
console.log(seconds);
seconds--;
}

Also, you want to console.log(seconds) instead of writing to the document. You won't need a line break if you use console.log.

Answer 3

function main() {
var seconds = parseInt(readLine(), 10)
// Your code here
while(seconds>=0); {
console.log(seconds);
seconds--;
}

}

Answer 4

This Correct

function main() {
var seconds = parseInt(readLine(), 10)
// Your code here
while(seconds>=0){
console.log(seconds)
seconds--
}
}

Answer 5

function main() {
var seconds = parseInt(readLine(), 10)
// Your code here
while(seconds>=0); {
console.log(seconds);
seconds--;
}

}
Outputs: Execution Timed Out!

I've tried every iteration I could think of...just lost at this point.

Answer 6

Thanks, mate!

Answer 7

No worries 🙂

Answer 8

function main() {
var seconds = parseInt(readLine(), 10)
// my code
while (seconds >= 0) {
console.log(seconds);
seconds--;
}
}

Good Luck

Pls 🙏🙏 I'm trying too hard to solve python times up test but still my output is
3
2
1
Instead of 3
2
1
0
I'm putting my code as 👇
# take the number as input
number = int(input())
#use a while loop for the countdown
while number > 0:
print(number)
number = number - 1
