Кофеварка с новым методом: ```js //+ run function CoffeeMachine(power) { this.waterAmount = 0; var WATER_HEAT_CAPACITY = 4200; *!* var timerId; */!* var self = this; function getBoilTime() { return self.waterAmount * WATER_HEAT_CAPACITY * 80 / power; } function onReady() { alert( 'Кофе готово!' ); } this.run = function() { *!* timerId = setTimeout(onReady, getBoilTime()); */!* }; *!* this.stop = function() { clearTimeout(timerId) }; */!* } var coffeeMachine = new CoffeeMachine(50000); coffeeMachine.waterAmount = 200; coffeeMachine.run(); coffeeMachine.stop(); // кофе приготовлен не будет ```
