Javascript Looping
=>While Loop
It loops through a block of code as long as the specified condition is true.
syntax:
  while(condition)
  {
    //block of code (code will execute until condition is true)
  }
 Examples:
   var countdown = 10;
   var i =0;
   while(i < countdown)
   {
    console.log(countdown);
    countdown--;
   }

   =>Do-While Loop
   It will execute the body first then checks the condition satisfies or not.
   syntax:
   do{
    //block of code
   }while(condition)
   Example:
   let count =0;
   do{
    console.log(count);
    count ++;
   }while(count<5)

=>Math.floor (It takes base values and if it is negative value then it takes next nearest integer)
console.log(Math.floor(5.9));//5
console.log(Math.floor(-4.9));//-5
=>Math.ceil
console.log(Math.ceil(5.1));//6
console.log(Math.ceil(-4.9));//-4
=>Math.round
console.log(Math.round(5.4));//5
console.log(Math.round(6.6));//7
=>Math.sqrt
console.log(Math.sqrt(0));//
console.log(Math.sqrt(-2));//
console.log(Math.sqrt(25));//
=>Math.cbrt
console.log(Math.cbrt(27));
console.log(Math.cbrt(125));
console.log(Math.cbrt(-125));
==>Math.abs
