Question

I am trying to update a variable every one second. For that reason I am using setTimeout. But it does not update the variable. It logs out 0 just once. Here is my code

var yes=0;
setTimeout(function () {
    console.log(yes);
    yes++;
}, 1000);​

Answer 1

Use setInterval, to finish the repitition you have to clear the interval using clearInterval(yourInterval);

Live Demo

var yes=0;
yourInterval = setInterval(function () {
    console.log(yes);
    yes++;
}, 1000);​
