I have two constructor functions here: Car and Van

    var Car = function (location) {
        this.loc = location
    };

    Car.prototype.move = function () {
        this.loc++
    }

    var Van = function (location) {
      Car.call(this, location)
    }

Could you tell me what this line Car.call(this, location) is doing? My assumption is that we want to inherit the loc property from the Car class to the Van class.

My confusion is on what now this inside

    Car.call(this, location)

is referring to? and also what this inside Car

    var Car = function (location) {
        this.loc = location
    };

is referring to? Can someone provide any insight?
