function | A network function is a function block that is encapsulated in the language to facilitate the user's invocation. For example, "Now" in VBScript is a function that shows the current date and time. As for the specific reason for the display,

The role of "styling" (Cast) is to "match a model". When appropriate, Java converts one data type automatically to another. For example, suppose we assign an integer value to a floating-point variable, and the computer automatically converts the int

javascript| Tutorial The JavaScript language is object-based (object-based) rather than object-oriented (object-oriented). It is said to be an object-based language, mainly because it does not provide many features such as abstraction, inheritance,
