This article brings you a comparison of the differences between json and XML. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
XML definition
Extensible Markup Language (XML) is a markup language used to mark electronic documents to make them structural. It can be used to mark data and define data. Type is a source language that allows users to define their own markup language.
JSON definition
JSON (JavaScript Object Notation) is a lightweight data exchange format that has good readability and is easy to write quickly. Data exchange between different platforms is possible. JSON adopts a highly compatible and completely language-independent text format, and also has behavior similar to C language habits (including C, C, C#, Java, JavaScript, Perl, Python, etc.). These properties make JSON an ideal data exchange language.
Advantages and Disadvantages of XML and JSON
Advantages of XML
A. The format is unified and compliant with standards;
B. Easy to integrate with other systems Remote interaction and data sharing are more convenient.
Disadvantages of XML
A.XML files are huge, the file format is complex, and transmission takes up bandwidth;
B.Both the server and the client need to spend a lot of code to parse XML , causing the server-side and client-side codes to become extremely complex and difficult to maintain;
C. The way of parsing XML between different browsers on the client side is inconsistent, and a lot of code needs to be written repeatedly;
D. Server-side and client-side Parsing XML takes more resources and time.
Advantages of JSON:
A. The data format is relatively simple, easy to read and write, the formats are compressed, and takes up little bandwidth;
B. Easy to parse, client JavaScript can simply read JSON data through eval();
C. Supports multiple languages, including ActionScript, C, C#, ColdFusion, Java, JavaScript, Perl, PHP, Python, Ruby and other server-side languages. Convenient for server-side parsing;
D. In the PHP world, PHP-JSON and JSON-PHP have already appeared. It is preferable to directly call the program after PHP serialization. PHP server-side objects, arrays, etc. can directly generate JSON format. Convenient for client access and extraction;
E. Because the JSON format can be directly used by server-side code, it greatly simplifies the code development of server-side and client-side, and the task remains unchanged and is easy to maintain.
Disadvantages of JSON
A. It is not as popular and widely used as XML format, and it is not as versatile as XML;
B.JSON format is currently used in Web Service Promotion in China is still in its infancy.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

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.
