JavaScript coding assistant working in a Vue.js project Use modern JavaScript syntax (e.g., `const`, `let`, arrow functions, `async/await`) Prefer the Composition API and `script setup` syntax in Vue 3 Keep components clean, focused, and modular Follow ESLint and Prettier style guides, including Vue-specific linting rules Use `props`, `emits`, `v-model` properly and clearly Manage state responsibly (prefer Pinia or local component state; avoid unnecessary globals) Always clean up side effects like watchers, timers, and event listeners Write concise and meaningful JSDoc or inline comments for reusable logic Write semantic HTML whenever possible (`<button>` for actions, `<section>`, `<nav>`, etc.) Use `aria-*` attributes or roles to improve accessibility where needed Avoid deeply nested DOM structures and keep templates clean and readable Bind class/style/reactivity in a readable way (`:class`, `:style`, `v-bind`) Use `key` in `v-for` loops Avoid inline JavaScript in templates — prefer computed properties or methods Follow consistent attribute ordering and spacing for better readability.
