Cli.ts

Make sure to use the answers parameter passed to your .then method to know which vehicle was selected. IF the vehicle selected is the truck, assign it to a variable and say that the truck cannot itself be towed. IF the vehicle selected is NOT the truck, find it and assign it to a variable. Have the user selected the vehicle that will be towed. Call the .tow method on the truck i.e. truck.tow(selectedVehicle).

     .then((answers) => {
        // BUG: use `answers.vehicleToTow` to check which vehicle was selected
       // IF that vehicle is the truck then show your message
        // TODO: check if the selected vehicle is the truck
        // TODO: if it is, log that the truck cannot tow itself then perform actions on the truck to allow the user to select another action
        let truckTowing = false;
        for (let i = 0; i < this.vehicles.length; i++) {
            if (this.vehicles[i].vin === this.selectedVehicleVin  && this.vehicles[i] instanceof Truck) {
              console.log(`Truck cannot tow itself. Select a different vehicle to tow.`);
              truckTowing = true;
             return;
            } 
        } 
        // TODO: if it is not, tow the selected vehicle then perform actions on the truck to allow the user to select another action
        // BUG we need a loop FIND the truck (if it wasn't already selected).
         for (let i = 0; i < this.vehicles.length; i++) {
            if (this.vehicles[i].vin != this.selectedVehicleVin && this.vehicles[i] !instanceof Truck) {
                console.log(`The ${this.vehicles[i].make} ${this.vehicles[i].model} is ready to tow.`);
                return;
          // BUG: once we have the Truck in a variable then we can call `tow` as a method i.e. truck.Tow(selectedVehicleToBeTowed)
             tow(Truck);             
            } 
          }

        })

Hi Nathan,

Thank you for your help.

I was able to get part of findVehicleToTow to work by using answers.vehicleToTow.

I tried let towTruck = Truck; towTruck.tow(answers.vehicleToTow).

Error message: Property 'tow' does not exist on type 'typeof Truck'.ts(2339)

Tried

var towTruck = this.selectedVehicleVin; towTruck.tow(answers.vehicleToTow);

Error messages: 'towTruck' is possibly 'undefined' and Property 'tow' does not exist on type 'string'.

Also tried

var towTruck = answers.vehicleToTow; towTruck.tow(this.selectedVehicleVin);

TypeError: towTruck.tow is not a function.

@natescode I figured out the issue and got tow & wheelie to work!
