PrefaceWhen you are learning JavaScript, you often encounter code for self-execution of anonymous functions. Today we will focus on self-execution.Before learning about this in detail, let's talk about the "self-execution" method. This article is

Phase 1:Copy codeThe Code is as follows:Function (){This. funB = function (){Alert ('a: funb ');};}A. prototype = {FunA: function (){Alert ('a: funa ');}};Function B (){}Function extend (sub, parent ){Sub. prototype = new parent ();Sub. prototype.

This article mainly introduces the use of arguments and jcalleecaller in js. For more information, see arguments, callee, and caller. Arguments: parameters of the Input Function Callee: the statement that represents the function and the function

In the strict JavaScript mode, some restrictions are imposed on JavaScript writing. If these restrictions are violated in the strict mode, the code will report an error. If you are interested in the knowledge of the strict mode of javascript, learn

First, file format1. For files that contain only PHP code, we will ignore "?>" at the end of the file. This is to prevent extraneous spaces or other characters from affecting the code.For example:$foo = ' foo ';2. Indentation should be able to

I quickly introduced some features of Lua. If you want to learn Lua quickly, we recommend that you read it first. 1. {}, constructor {A = 1, B = 2} is equivalent to {["a"] = 1, ["B"] = 2} {"X", "y", "z"} is equivalent to {[1] = "x", [2] = "y", [3] =

I've been learning for a long time. C + + Sometimes the pointer is a bit messy.I hope the great God finds out if there is something wrong below. I find that the reason why I am disorderly is because the Chinese language is inaccurate, for example,

Chapter fourth variable/scope and memory issues1. When assigning a value to another variable from one variable, if it is an assignment of the base type value, a copy of the value is created, and two variable operations do not affect each other. If

Basic usageES6 allows you to define functions using the arrows ( => ).var f = v + V;The above arrow functions are equivalent to:var function (v) { return v;};If the arrow function does not require arguments or requires more than one argument, a

The memory mechanism of C and C ++ is very similar, but there are still some differences. Let's take a look at the differences between them. (1) c memory mechanism 1. STACK: local variables (including function arguments) in the function are

Javascript has been used for more than three years, but some details are still unknown, such as objects and arrays, and some basic operations are always used. This is a bad habit for me to learn-lazy. Many things only know about it, and there is no
