JavaScript’s evolution is gradual but steady. Over the past ten years, JavaScript has gradually developed from a simple toy-like language in people's perception to a highly respected programming language, used by companies and developers around the world to construct all kinds of incredible things. application. The modern JavaScript programming language remains as reliable, robust, and incredibly powerful as ever. Much of what I discuss in this book will reveal what makes modern JavaScript applications so distinctly different from those of the past. Many of the concepts presented in this chapter are far from novel, but the recognition of thousands of smart programmers has helped to sublimate their use and ultimately form the pattern today. That being the case, let’s just focus on modern JavaScript programming.
Chapter 1: Modern JavaScript Programming
This book attempts to completely cover all modern, professional JavaScript programming techniques with the goal that they will be used by everyone from independent developers to large companies Use it to make its code more usable, readable, and interactive.
In this chapter we give a brief overview of each knowledge point that will appear in this book. This covers the basics of professional JavaScript programming: writing object-oriented code, testing the code, and packaging it for distribution. You then saw the main aspects of Unobtrusive DOM scripting, including a brief overview of the Document Object Model, events, and JavaScript interaction with CSS. Finally you saw the premise behind Ajax and JavaScript support in modern browsers. Taken together, these topics are enough to help you become a professional JavaScript programmer.

计算机编程中常见的if语句是什么Jan 29, 2023 pm 04:31 PM计算机编程中常见的if语句是条件判断语句。if语句是一种选择分支结构，它是依据明确的条件选择选择执行路径，而不是严格按照顺序执行，在编程实际运用中要根据程序流程选择适合的分支语句，它是依照条件的结果改变执行的程序；if语句的简单语法“if(条件表达式){// 要执行的代码;}”。
Python编程：详解命名元组（namedtuple）的使用要点Apr 11, 2023 pm 09:22 PM前言本文继续来介绍Python集合模块，这次主要简明扼要的介绍其内的命名元组，即namedtuple的使用。闲话少叙，我们开始——记得点赞、关注和转发哦~ ^_^创建命名元组Python集合中的命名元组类namedTuples为元组中的每个位置赋予意义，并增强代码的可读性和描述性。它们可以在任何使用常规元组的地方使用，且增加了通过名称而不是位置索引方式访问字段的能力。其来自Python内置模块collections。其使用的常规语法方式为：import collections XxNamedT
如何在Go中进行图像处理？May 11, 2023 pm 04:45 PM作为一门高效的编程语言，Go在图像处理领域也有着不错的表现。虽然Go本身的标准库中没有提供专门的图像处理相关的API，但是有一些优秀的第三方库可以供我们使用，比如GoCV、ImageMagick和GraphicsMagick等。本文将重点介绍使用GoCV进行图像处理的方法。GoCV是一个高度依赖于OpenCV的Go语言绑定库，其
PHP8.0中的DOMDocumentMay 14, 2023 am 08:18 AM随着PHP8.0的发布，DOMDocument作为PHP内置的XML解析库，也有了新的变化和增强。DOMDocument在PHP中的重要性不言而喻，尤其在处理XML文档方面，它的功能十分强大，而且使用起来也十分简单。本文将介绍PHP8.0中DOMDocument的新特性和应用。一、DOMDocument概述DOM(DocumentObjectModel)
学Python，还不知道main函数吗Apr 12, 2023 pm 02:58 PMPython 中的 main 函数充当程序的执行点，在 Python 编程中定义 main 函数是启动程序执行的必要条件，不过它仅在程序直接运行时才执行，而在作为模块导入时不会执行。要了解有关 Python main 函数的更多信息，我们将从如下几点逐步学习：什么是 Python 函数Python 中 main 函数的功能是什么一个基本的 Python main() 是怎样的Python 执行模式Let’s get started什么是 Python 函数相信很多小伙伴对函数都不陌生了，函数是可
为拯救童年回忆，开发者决定采用古法编程：用Flash高清重制了一款游戏Apr 11, 2023 pm 10:16 PM两年多前，Adobe 发布了一则引人关注的公告 —— 将在 2020 年 12 月 31 日终止支持 Flash，宣告了一个时代的结束。一晃两年过去了，Adobe 早已从官方网站中删除了 Flash Player 早期版本的所有存档，并阻止基于 Flash 的内容运行。微软也已经终止对 Adobe Flash Player 的支持，并禁止其在任何 Microsoft 浏览器上运行。Adobe Flash Player 组件于 2021 年 7 月通过 Windows 更新永久删除。当 Flash
学编程什么年龄最适合？Sep 27, 2022 pm 02:49 PM学编程任何年龄都适合，没有年龄限制。学编程什么年龄都可以学，都适合学，无论你是零基础还是有基础，只要选对合适的编程课程，不管什么年龄都能学会；想做的事情就去做，不要因为过多的担忧而放弃改变，否则错失机会，只会导致更多遗憾。
Python编程：轻松搞透上下文管理器（Context Manager）Apr 12, 2023 pm 02:07 PM前言本文聚焦在Python的上下文管理的讲解和应用。还是通过代码实例的方式，对照理解和学习，以达到“多快好省”的理解、掌握和应用。闲话少叙，开始——1.何为上下文管理器上下文管理器是一个对象，它定义了在执行with语句时要建立的运行时上下文。上下文管理器是为代码块所执行的上下文环境自动处理进入和退出所需的运行时。上下文管理器通常使用with语句调用，但也可以通过直接调用它们的方法来使用。上下文管理器的典型用途包括保存和恢复各种全局状态，锁定和解锁资源，关闭打开的文件，等等。在章节中，我们将学习如

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
