First, we should explain the characteristics of the closure, so we should better understand the two features of the closure: 1. As a reference to a function variable-when the function returns, it is in the active state. 2. A closure is a stack that

1. Different identifiers. The identifier of the FUNCTION is FUNCTION and the process is PROCEDURE. 2. In a function, variable parameters are generally not used, and function values are directly returned using the function name. 1. Different

In any programming language, the use of functions is mainly due to the following two scenarios: code block duplication, it is necessary to consider the use of functions to reduce the redundancy of the program code block is complex, this

Functions are the basis for modular programming, and for writing complex AJAX applications, you must have a deeper understanding of the functions.The functions in JavaScript are different from those of other languages, and each function is

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.
