Loop timeout delay in Browser Console

Below code will iterate from 1 to 10 with a delay of 1 second (1000 ms) between each iteration.

function loopFinish() {
   console.log('All is complete');
}
for(let i = 1; i < 11; i++) {
   setTimeout(()=>{

      }
   },i * 1000);
}

Iteration number: 3
Iteration number: 4
Iteration number: 5
Iteration number: 6
Iteration number: 7
Iteration number: 8
Iteration number: 9
