javascript - Applying a function to a nested loop -

//problem 3a:  (var a=1; a<12; a++) {      (var b=00; b<60; b++) {          (var c=00; c<60; c++) {              console.log(a + ':' + b + ':' + c + 'am');          }      }  }  (var alpha=12; alpha<13; alpha++) {      (var x=00; x<60; x++) {          (var y=00; y<60; y++) {              console.log(alpha + ':' + x + ':' + y + 'pm');          }      }  }  (var d=1; d<13; d++) {      (var e=00; e<60; e++) {          (var f=00; f<60; f++) {              console.log(d + ':' + e + ':' + f + 'pm');          }      }  }    //problem 3b:  function onetotwo(number) {      if (number < 10 && number >= 0) {          return '0' + number;      } else           return number;      }    //now apply problem 3a:  (var q=0; q<10; q++) {      onetotwo(q);     }

i beginning learn javascript , have written loop output should seconds in every minute in every hour in 1 day, on 12-hour clock. second part of question write function turns 1 digit number respective 2 digit number. think have written both of these correctly, having trouble applying loop. can me please???

for loop , function

you can use

setinterval(function(){ alert("hello"); }, 1000);

1000 refers 1000 ms 1 second

you can replace function(){} function name

<script>setinterval(function(){ console.log(new date().tolocaletimestring());+"\n"; }, 1000);</script>
