: The instance method of JS must use the This keyword, and the class's methods usually do not use the This keyword, they refer to its parameter operation;The P222-based inheritance mechanism in the extended p223js of class 9.4 is dynamic: Objects inherit properties from other prototypes, and if the properties of the prototype change after the object is created, it also affects all instance objects that inherit the prototype, and we can augment the JS class by adding a new method to the prototype

belongs to the comparison sort. At the same time, fast sorting has in-situ sorting and instability, which means that no additional sort space is required for fast sorting, but it is not guaranteed that equal element positions are not exchanged.Answer:Fast sorting is one of the most efficient internal sorting algorithms, and its basic idea is to divide the sorted object into two columns of sub-sequences, and one of the subsequence values is greater than the value of another subsequence, and furt

hidden file plugin I have not heard of. But I thought that since I was trying to hide the file, the goal was not to like others to find out, of course, the complexity is better. The MV command is used to move the file, but if it is still under the same path, it is usually named "." In the Mac. The beginning of the file is a hidden file, so we can use the MV command to achieve file hiding. For example, there is a file named tool, I want to hide, you should go to the tool path, such as tool in th

As shown below:Class _jobject {}; Class _jclass:public _jobject {}; Class _jstring:public _jobject {}; Class _jarray:public

disadvantage of using macro code is error-prone, and the preprocessor often produces unintended marginal effects when copying macro code. In a C + + program, you should replace all macro code with an inline function, and assert assert is probably the only exception. member functions defined in the class declaration will automatically become inline functions The C + + compiler will automatically generate four default functions for a, such as A (void); Default parameterless constructo
