For Loop Set Timeout With Code Examples

In this session, we’ll attempt our hand at fixing the For Loop Set Timeout puzzle through the use of the pc language. The code that follows serves for instance this level.

operate timeout() {
    setTimeout(operate () {
        // Do Something Here
        // Then recall the mum or dad operate to
        // create a recursive loop.
        timeout();
    }, 1000);
}

There are various totally different approaches one can take to fixing the identical drawback For Loop Set Timeout. The following paragraphs will study the varied different potential options.

// ensure to make use of "let" and never "var" if you wish to seize
// the worth of the exterior variable in a closure

  for (let i = 0; i < 5; i++) {
    setTimeout(() => console.log(i), 0);
  }
for(var i = 1; i < 6; i++) {
  setTimeout(operate() {
     console.log(i);
  },1000);
}
console.log('The loop is completed!');
window.purls = [11213,23121,43343,5644,77535]
i = 0;
for (i = 0; i < window.purls.size; i++){
    doSetTimeout(i);
}

operate doSetTimeout(i) {
	setTimeout(operate() {
		// Code goes right here
	}, i*1200); //1200 = time in milliseconds
}
var time = 1;

var interval = setInterval(operate() { 
   if (time <= 3) { 
      alert(time);
      time++;
   }
   else { 
      clearInterval(interval);
   }
}, 5000);

We have demonstrated, with a plethora of illustrative examples, sort out the For Loop Set Timeout drawback.

Can I take advantage of setTimeout in for loop?

The setTimeout operate callback is not triggered till the for loop execution has accomplished. When the for loop has completed executing the worth of i is 7.
