Preface When you are learning JavaScript, you often encounter self-executed anonymous functions.CodeToday, we will focus on self-execution. Before learning about this in detail, let's talk about the "self-execution" method. This article is not

Some summaries after online review, not originalIn general, we need to invoke a JavaScript function, the basic condition is defined first, and then called.If you do not need to display the calling function, so that the function is executed at the

Seeing the const keyword, the first thing a C + + programmer might think of is a const constant. This is not a good reflex. If you only know to define constants with const, then it is equivalent to using gunpowder only to make firecrackers. The

First, read the following eight questions. If you can do it without reading any materials. Congratulations! It should be okay. Because the complex combinations are all changed from the above eight types. 1. Define an integer 2. Define a pointer to

Program memory Layout-the point of the function call stack, the memory layout function call [Note] This article is a summary of "programmer's self-cultivation", which is mixed with some personal understandings. If there is anything wrong, you are

Nonsense article:Today I saw the prototype chain of JavaScript, various points, all kinds of objects have wood, all kinds of halo, all kinds of confusion have wood. Part-time is a challenge to the limits of a person's brain warp. However, the

In this paper, the usage of virtual function and pure virtual function in C + + is deeply analyzed, which is very important for learning and mastering object-oriented programming. The specific contents are as follows: First, the core idea of object-

The code for the JS anonymous function is as follows :(function () {This ignores all implementations of JQuery})();When I first contacted jQuery six months ago , I was as excited as anyone to see what the source code was like. However, at the first

The address of the virtual function is not necessarily saved in the virtual function table. I always thought that the address of the virtual function is saved in the virtual function table. I did not find this idea correct when I did a test a few
