In recent years, the Internet has developed rapidly, and front-end development has received more and more attention. So, what is front-end development? To put it simply, it is to use some programming languages (such as HTML, CSS, JavaScript) to develop web pages and create the effects that users ultimately see.
Front-end skills can be divided into three levels: basic skills, advanced skills and advanced skills.
1. Basic skills
- HTML: The structure and content of web pages are determined by HTML.
- CSS: CSS controls the style of web pages, including fonts, colors, margins, layout, etc.
- JavaScript: JavaScript is used to achieve interactive effects on web pages.
- Web Security: Learn how to keep your website secure.
- How the browser works: Understanding the structure and working principle of the browser can better optimize web page performance.
2. Advanced Skills
- Responsive Web Design: The website can adapt to devices with different screen sizes.
- CSS preprocessor: Use LESS, SASS and other tools to simplify CSS writing and debugging.
- Front-end framework: such as React, Vue, etc., used to speed up development efficiency.
- Webpack: can automatically build front-end projects.
- Ajax: Asynchronous data interaction without refreshing the page.
3. Advanced skills
- Mobile terminal development: Understand the characteristics and technologies of mobile terminals, and create web pages and applications suitable for mobile devices.
- Server-side rendering (SSR): Use Node.js to render web pages to improve page loading speed and SEO optimization effects.
- PWA: Progressive Web Application, which can improve user experience offline.
- Website performance optimization: Use some technologies (such as caching, CDN, etc.) to optimize website performance and improve page loading speed.
- Web authentication: such as OAuth2.0, JWT, etc., to ensure the security of the website.
In short, front-end development is a very important skill, which is very useful both at work and in personal hobbies. If you want to become an excellent front-end developer, it is recommended that you have a strong desire for knowledge, a spirit of continuous learning, and a rigorous work attitude, so that you can continuously improve your abilities.

React's One-Way Data Binding: Ensuring Predictable Data FlowApr 28, 2025 am 12:05 AMReact's one-way data binding ensures that data flows from the parent component to the child component. 1) The data flows to a single, and the changes in the state of the parent component can be passed to the child component, but the child component cannot directly affect the state of the parent component. 2) This method improves the predictability of data flows and simplifies debugging and testing. 3) By using controlled components and context, user interaction and inter-component communication can be handled while maintaining a one-way data stream.

Sharing State Between Components Using Context and useState()Apr 27, 2025 am 12:19 AMUse Context and useState to share states because they simplify state management in large React applications. 1) Reduce propdrilling, 2) The code is clearer, 3) It is easier to manage global state. However, pay attention to performance overhead and debugging complexity. The rational use of Context and optimization technology can improve the efficiency and maintainability of the application.
The Impact of Incorrect Keys on React's Virtual DOM UpdatesApr 27, 2025 am 12:19 AMUsing incorrect keys can cause performance issues and unexpected behavior in React applications. 1) The key is a unique identifier of the list item, helping React update the virtual DOM efficiently. 2) Using the same or non-unique key will cause list items to be reordered and component states to be lost. 3) Using stable and unique identifiers as keys can optimize performance and avoid full re-rendering. 4) Use tools such as ESLint to verify the correctness of the key. Proper use of keys ensures efficient and reliable React applications.

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),
DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
