If we want to print numbers such as 1 through ten. Yes we can type console.log(1) and retype it ten 10 time. However, we wan tto save data and avoid repetion of code.

1. For(initialize;test; increment/decrement
   decrement) {// code Block//}
2. Eample standard For Loop
3. for(var i = 0; i < i; i++ {
   console.log(i);} // this will print the number from 1 thourgh 10.)
4. We use i, because that is short for index

The loop then performs some action, which affects that condition repeatedly until that condition becomes false.

for (var i =0; i < 11; i++) {
console.log(i);
}

var roopak = ['Roopak', 'kumar', 1990, 'student', true];
for (var i = 0; i < roopak.length; i++) {
console.log(roopak[i]);
}


//While Loop

var i = 0;
while(i < roopak.length) {
console.log(roopak[i]);<br /> i++;
}
