Write some JavaScript that uses the current clock and gives an alert message whether the science class is over (Assume class ends at 02:30).

Ans: Possible solution:

var cTime = new Date();

var hour = cTime.getHours();

var mins = cTime.getMinutes();

if (hour > 12 || hour == 12 && mins > 20) {

alert(“Yay, science class got over!!”);

} else {

alert(“Hang on, the science class is yet to finish!”);

}
