// var i = 0; -> initial value of the loop statement : i === 0 | |
// executed before the first iteration | |
// i < 9 -> condition that must be true for the loop to proceed : check if i is less than 9 | |
// if it is not less than 9, end the loop | |
// if it is less than 9, do the thing inside the loop : | |
console.log('The current value of i is :', i) | |
// i++ -> post statement (executed at the end of an iteration) : increment i by 1 (i++ is the same as i + 1) | |
