Owing to the seriousness of the case, Investigators expanded the scope of their search. Through continuous investigation of the surroundings, investigators accidentally found three brightly colored plastic bags in Wenliang River on the west side of the scene. The bags were basically filled with domestic garbage. Under these scattered items, they found a bank card of a rural credit cooperative. The last bag contained clothes, both men's and women's. In a pair of men's jeans, the investigators found another Agricultural Bank subsistence allowance card with a signature on the back. After identification, the clothes in the bag were exactly the clothes the couple had worn in recent days. What was even more shocking was that the bag also contained the marriage certificates of the couple. This is a dangerous signal, and the investigators' foreboding is getting stronger and stronger. The top priority is to find out where the missing couple are.
As seen above, we directly call that subclass baiDuInterview.init () method. Since our subclass baiDuInterview has no init method, but it inherit the parent class, we will look for the corresponding init method in the parent class. Therefore, it will face the prototype chain and look up in the parent class. The same is true for other subclasses, such as Ali class code, which will not be introduced much here. For the parent class, this method Interview.prototype.init () is a template method, because it encapsulates the algorithm framework in the subclass. As a template for an algorithm, it guides the subclass to execute the code in what order.
