Creating Objects ("JavaScript advanced Programming" mind mapping)

Object-oriented (object-oriented, OO) languages have a sign that they all have the concept of a class, and that a class can create any number of objects with the same properties and methods. There is no class concept in ECMAScript, so we can use objects to simulate the class. ECMA-262 defines an object as: "A collection of unordered attributes whose properties can contain basic values, objects, or functions." "Strictly speaking, this is equivalent to saying that the object is a set of values that do not have a particular order. Each property or method of an object has a name, and each name is mapped to a value.

Here are the methods of creating objects described in the JavaScript Advanced Programming program, which I have always formed in mind mapping mode:

The most widely used is the combination of the constructor pattern and the prototype pattern. In addition, the dynamic prototype pattern is also popular, functionally equivalent to the constructor mode/prototype mode. Either of these two approaches can be used. Do not use the classic constructor or prototype schema alone, however, because it introduces problems to your code.
