Article Introduction：ESLint is a static code inspection tool for JavaScript and JSX, which is mainly used to discover potential problems in the code and unify the code style. It not only checks for syntax errors, but also points out non-standard, prone to errors or in compliance with best practices based on configuration rules. Its core functions include: discovering common errors in advance (such as unused variables), unifying the code style, cooperating with the editor's real-time prompts, and supporting automatic fixes of some problems. The steps for use are: install ESLint, create configuration files, select rulesets, run check commands, and use them with the editor plug-in. Coping strategies include: adopting loose configurations to gradually strengthen rules, closing unwanted rules, and integrating in CI/CD to ensure uniform use of the team. Through reasonable configuration,

Article Introduction：C language identifier naming rules: consist of letters, numbers and underscores. The first character must be a letter or underscore and is case sensitive. The naming styles include camel, underlined and Hungarian nomenclature. It is recommended to use a concise and clear camel nomenclature, but team consistency is more important. Naming should be based on the name and avoid using meaningless identifiers. Naming style has nothing to do with performance, and the main purpose is to improve code readability and maintainability.

Both tools are based on Node.js and can be installed using npm. For small websites, many tool tagging issues can be ignored, but for large projects, they help prevent maintenance issues. Task runners or build systems such as Grunt, Gulp, and webpack can automate connections and optimization tasks, thereby reducing the use of s

Article Introduction：The main difference between Sass and SCSS is the syntax. SCSS uses curly braces {} and semicolon similar to standard CSS; to facilitate the transition from CSS, and supports direct copying of CSS code and adding variables, mixing and other functions; while Sass adopts indented syntax, no curly braces and semicolons are required, and relies on line breaks and spaces to define code blocks. It has a simpler style but is also easy to cause problems due to format errors. The two can be converted to each other through tools. Modern frameworks mostly use SCSS by default because they are easier to learn and have rich resources; file extensions are .sass and .scss respectively, and the choice should be based on personal or team preferences.

Article Introduction：The future development direction of CSS is exciting, and its core lies in the fact that language is gradually meeting the needs of modern web development. 1. The native cascade layer provides better style priority control to reduce specific conflicts; 2. The sub-grid supports the alignment of nested elements with the parent container to avoid redundant code; 3. Container query allows components to adapt based on container size to promote true component design; 4.:has() selector can set the conditional style according to the state of the internal element to reduce JavaScript dependencies. These features mark the positive evolution of CSS in a more expressive and logical direction. Some functions have been available in modern browsers. Familiarity with them in advance will help future project practices.

Article Introduction：Choosing a CSS framework or native CSS depends on project requirements and team proficiency. Using frameworks such as Bootstrap or Tailwind can speed up development with prefabricated components, especially for prototypes or time-critical projects, but requires learning naming specifications and tool patterns; while native CSS does not require additional syntax, suitable for small projects or situations where full control is required. Frameworks may cause code redundancy and need to be manually optimized to avoid performance problems, while native CSS is more flexible but is slow to develop and prone to inconsistent. In teamwork, frameworks help unify styles and simplify handovers, but over-customization can cause confusion, while native CSS is easier to debug due to its simple structure. Therefore, both have their own advantages and disadvantages, and should be based on development efficiency, customization, performance and
