   var arr = [];
   for (var i = 0; i < 50000; i++) {
       arr[i] = i;
   }
Tests:

  • while loop

     
    let i = 0
    while(i < arr.length) {
      arr[i]
      i++
    }

  • for loop

     
    for(let i = 0; i < arr.length; i++) {
        arr[i]
    }

  • do .. while loop

     
    let i = 0
    do {
      arr[i]
      i++
    } while(i < arr.length)

  • forEach loop

     
    arr.forEach((data) => {
        data
    })
