Prototype

可以使用原型模式来减少创建新对象的成本:

• Object.create().
• Object shallow clone.

class Car {
  constructor(name, model) {
    this.name = name
    this.model = model
  }

  SetName(name) {
    console.log(`${name}`)
  }

  clone() {
    return new Car(this.name, this.model)
  }
}

const car = new Car()
car.SetName('Audi')

const car2 = car.clone()
car2.SetName('BMW')
