compare two times to return boolean value as true or false

Question

I have time in the format "hh:mm" in 24 hr format. Now how to compare two times such that it returns the boolean value . And if both the times is same in hours then should compare minutes and return either true or false. Meaning t1="15:30" and t2="15:40" should return false if checking whether t1> t2 using javascript

Native JS Date objects can be compared using `>`, `==` and `<` — Tom Fenech, May 02 '14 at 10:18
24 hour format has the advantage that if you have them in string form, they'll compare correctly by just the regular string comparison operators. — Joachim Isaksson, May 02 '14 at 10:19

Dates that are formatted HH:mm (ie always 2 digit hours) with 24 hours time will compare correctly as strings without converting them;

var t1 = "15:30";
var t2 = "15:40";

console.log(t1 < t2);
console.log(t1 == t2);
console.log(t1 > t2);

> true
> false
> false

@user13763 No, only 24 hour format as stated in the question. – Joachim Isaksson May 02 '14 at 11:02
