What is a namespace?
The namespace (English: Namespace) represents the visible range of identifiers (identifier). An identifier can be defined in more than one namespace, and its meaning in different namespaces is mutually irrelevant. In this way, any identifiers can be defined in a new
Namespaces are actually just a form, and the ultimate goal is to refactor the code, but it's impossible to do this in a single pass.
At first, a pseudo proposition was given: thinkphp-based refactoring (not why). After a period of practice, it is found that this is a wrong way of thinking, in which the pits encountered in this slightly not table.
First, don't try to rewrite the whole namespace based on namespaces, but should be local.

C + + namespacesIn a C + + application. For example, you might write a function called Func () that also has the same function func () in another available library. This way, the compiler will not be able to tell which func () function you are using.Therefore, the concept of namespaces is introduced to solve the above problem, which can be used as additional information to distinguish functions, classes, variables, etc. of the same name in different libraries. The context is defined by using a
The basic methods of creating objects in JavaScript are literal declarations (object Literal) and constructors, but JavaScript does not have special syntax to represent concepts in object-oriented programming such as namespaces, modules, packages, private properties, static properties, and so on. To enable JavaScript to implement advanced semantics in object-oriented programs, people have invented namespace patterns, dependency declaration patterns, m
