Trying to solve time's up in JavaScript

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
_______________________________________________________________________________________________
function main() {
var seconds = parseInt(readLine(), 10)
// Your code here

while(4<=1){
documemt.write(1+"<br/>");
i++;
}
_______________________________________________________________________________________________
it showing unexpected end

Answer 1

1. Your while loop is not closed with a curly brace - }

2. The while loop condition is wrong.
4 is not less than or equal to 1, so the code in the while body will not be executed. It should be 4 >= 1.
Also in the place of 4, you should use the seconds variable, because 4 is a static value.
while (seconds >= 1), or better
while (seconds > 0)

3. You have a typo here: documemt.write(), instead
document.write()
But you must log the result in the console.
So, you need to use console.log(), as such:
console.log(seconds)

4. You don't have declared 'i' variable, so there is no point to increase i++, since it's not used.
Instead you have the seconds variable which you need to decrease on each iteration of the loop.
seconds--;

In the end the loop should look like this:
while (seconds > -1) {
console.log(seconds);
seconds--;
}

Or just:
while (seconds > -1) console.log(seconds--);

Answer 2

Maybe will be needed setInterval(), then this can be help:

Answer 3

First of all in the while loop you should have a variable for control.

Thanks for your help

Answer 6

what do you think should be changed?

Answer 7

.ym .g.

M v

Answer 8

How?

Answer 9

Don't know exactly

Answer 10

Boris Batinkov
Tried this
function main() {
var seconds = parseInt(readLine(), 10)
// Your code here

while(seconds>0)console.log(seconds--);
}
But it counts
5
4
3
2
1
And does not include 0

Answer 11

Hi! assign an initial value to the variable "i", then use it in the while loop condition, as well as for output to the screen

Answer 12

In this task variable "seconds" used instead of the "i" variable

Answer 13

Yaroslav Vernigora i have changed the i to seconds still no difference

Answer 14

Show your fixed code again

Answer 15

function main() {
var seconds = parseInt(readLine(), 10)
// Your code here

while(4<=1){
documemt.write(1+"<br/>");
seconds++;
}

Answer 16

explain in your own words your condition in the loop. what's in parentheses. what does your condition do?

Answer 17

Its counts down from 4

Answer 18

"it's count down from 4"
idk why would you say it counts starting from 4 because you made a typo in document.type syntax! which means it will never print the number and the while loop doesn't have a closed curly bracket so the browser doesn't have a damn clue where to end.

you can try doing it. or you can see the code

Answer 19

1. read the lesson about the while loop again, see the sample code, how it works

2. make a normal working condition of the loop

3. think if you have 4 seconds, and you need to do a countdown, should the seconds increase or decrease?

4. change document.write to console.log here as well

Answer 20

the test program does not skip document.write() instead, use console.log()
