You are a leader of a small pirate crew. And you have a plan. With the help of OOP you wish to make a pretty efficient system to identify ships with a heavy booty on board.

Unfortunattely for you, people weigh a lot this days, so how do you know if a ship if full of gold and not people?

You begin with writing a generic Ship class:

function Ship(draft,crew) {
 this.draft = draft;
 this.crew = crew;
}
Every time your spies see a new ship enter the dock, they will create a new ship object based on their observations:

draft - an estimate of the ship's weight based on how low it is in the water
crew - the count of crew on board
var titanic = new Ship(15, 10);
Taking into account that an average crew member on board adds 1.5 units to the draft, a ship that has a draft of more than 20 without crew is considered worthy to loot. Any ship weighing that much must have a lot of booty!

Add the method

isWorthIt
to decide if the ship is worthy to loot. For example:

titanic.isWorthIt() // return false
*/

//Answer//

function Ship(draft,crew) {
 this.draft = draft;
 this.crew = crew;
}

Ship.prototype.isWorthIt = function Ship(draft,crew) {
return this.draft-(this.crew*1.5)>20
}
