In the following code fragment, where we use
setInterval
, one line is missing – the place is marked in gray:
let counter = 2; let interval = setInterval(() => { console.log(counter); }, 1000);
What should the missing line look like if the execution of this code results in the console displaying the values 2
, 1
, and 0
in sequence?
if (counter-- <= 0) clearInterval(interval);
while (counter-- >= 0) clearInterval(interval);
clearInterval(interval);
if (counter-- >= 0) clearInterval(interval);
