js最后一行哪里出错了 报错显示car不是构造函数

Question

Car.prototype.height = 1400;
Car.prototype.lang = 4900;
Car.prototype.carName="BMW"
function Car (color, owner) {
this.color = color;
this.owner = owner;
var Car = new Car ('blue', 'Mini' );
var Car1 = new Car ('red', 'wife' );

Answer 1

var Car = new Car('blue', 'Mini' );
变量名与构造函数名同名了
Car 被重新赋值成类的实例对象了，之后再调用Car就不是构造函数了。

function Car (color, owner) {
    this.color = color;
    this.owner = owner;
}
Car.prototype.height = 1400;
Car.prototype.lang = 4900;
Car.prototype.carName="BMW";

var Car0 = new Car('blue', 'Mini' );//不要同名即可
var Car1 = new Car('red', 'wife' );
