The use of the Const keyword in C + + is very flexible, and using the const will greatly improve the robustness of the program, I found in various aspects of the information summarized below, hoping to help friends.Const is a type modifier commonly

The core realization of RequirejsThe module can be abstracted into the following objectA module can be understood as a JS file, with three properties: Deps (Dependency of the module), callback (the module's callback, after all dependent load

This paper explains the modularization of JavaScript, which is as follows:
AMD is requirejs in the promotion process of the modular definition of the standardized output.

This note is summarized from a code view.
In general, when programming with C, we are used to defining a numeric constant in our code using the macro definition in C:
#define MY_CONST 7
When developing a project in C + +, there is
In C + +, we can define the so-called symbolic constants by #define This instruction, which is directly compiled into binary code. In this case, it is basically the same as the effect of the constant value variable defined with Const. Of
For
AMD (Asynchronous module definition) is the normalized output defined by Requirejs in the promotion process.function (Lib) { function foo () { lib.log (' Hello world! ') ); } return { foo:foo };});CMD (Synchronous module definition)
Some people complain that the Linux system does not resemble VC and other convenient and quick editor, someone with Gedit, some use vim, but are not convenient and there is no automatic completion of the user-friendly functions such as the user.
The difference is as follows:
Constants defined with #define MAX 255 are of no type , given an immediate number, and the compiler simply links the defined constant value to the name of the defined constant, define the defined macro variable to be

Scalar type declaration
There are two modes: mandatory (default) and strict mode. You can now use the following type parameters, whether in mandatory or strict mode: string, Integer (int), floating-point number (float), and Boolean value (BOOL). In
Non-organized functions
When I first started writing JavaScript functions, this is usually the case:
The code is as follows
Copy Code
function Fun1 () {Some code here}function fun2 () {Some other code here}...
Introduced
It is well known that the front-end development of modularity is the trend, the current modular norms have a lot of well-known commonjs,module/wrappings and AMD, and ES6 also started to develop the implementation of the modular mechanism.
