object-orientedJS has no classes, but to make it easier to familiarize yourself with the class (object-oriented code), you can use the new operand to build the object, just as in Java, a special constructor constructor is defined after the new operand. However, even without constructors, you can create objects and set properties, and the properties and methods of JS objects can be added and deleted at any time.

node tree have hierarchical relationships with each other.Terms such as the parent, Son (Child), and fellow (sibling) are used to describe these relationships. The parent node has child nodes. Child nodes of a sibling are called siblings (brothers or sisters). In the node tree, the top node is called root (root) Each node has a parent node, except for the root (it has no parent node) A node can have any number of sub- A sibling is a node that has the same parent node T
