Constructor Mode
The constructor is a special function used to initialize a new object when the memory of the new object is allocated. The object constructor is used to create special types of objects. First, it needs to prepare the objects to be used. Second, when an object is first created, it receives parameters, the constructor is used to assign values to attributes and methods of members.

The constructor mode is described in the following figure ):
Constructor cannot be inherited, so Overriding cannot be overwritten, but Overloading can be overloaded. The constructor is used to create objects of specific types-prepare objects for use and receive parameters that can be used by the constructor to set the value of member attributes and methods when creating objects for the first time.

Class concept, but it also supports object creation with constructor.
By using the [new] keyword, we can make a function behave like a constructor to create its own object instance.
The following is a basic constructor:
Function Car (model, year, miles) {// here, this points to the newly created object itself this. model = model; this. year = year; this. miles = miles; this. toString = function () {return this. model + "has done" + this. miles + "miles" ;};}// usage // create two car instances
= function () {return this. model + "has done" + this. miles + "miles" ;};}; // usage // you can create a new car instance var civic = new Car ("Hona Civic", 2009,2000 ); var mondeo = new Car ("Ford Mondeo", 2010,5000); console. log (civic. toString (); console. log (mondeo. toString ());
3. Constructor with prototype
JavaScript has the prototype attribute. And

What we are most familiar with encryption assets is the encrypted currency. But is it safe to use it as an encrypted currency? As a matter of fact, since the advent of the first cryptocurrency bitcoin, there have been many digital currency theft incidents, and some even the entire exchange has been attacked. Encrypted currencies have all disappeared overnight.

Why you want to learn blockchain technology development. Before you answer this question, you need to point out:
Blockchain is now an over-valued area, and these overvalued values are unsustainable and will certainly collapse.
