开发Three.js 3D编辑器：选UI框架还是原生JS构建动态复杂UI？

Hey there! Let's break this down based on your specific situation—you're already solid with Three.js and vanilla JavaScript, but new to UI frameworks and need to build some complex dynamic UIs like tutorial wizards, consoles, and dynamic form fields. Here's my take:

Why a framework like React or Vue is likely the better bet for your project #

• State management takes the pain away
  Your dynamic UIs (like switching tutorial steps, updating console logs, or adding/removing form fields) rely heavily on syncing data with the UI. Frameworks handle this automatically: React's useState/useReducer or Vue's reactive data will update the UI the second your data changes, no manual DOM manipulation or event listener cleanup required. You'll avoid the common vanilla JS pitfalls of "data changed but UI didn't" or messy state tracking.

• Componentization cuts down on repetition
  Think of your tutorial wizard steps, console log entries, or dynamic input fields—these are all reusable chunks of UI. With frameworks, you can wrap each into a small, self-contained component (like <TutorialStep> or <ConsoleLogItem>) and reuse them anywhere. No more copying and pasting DOM creation code, and making changes later only requires updating one component instead of hunting through hundreds of lines of vanilla JS.

• Ecosystem tools save you time
  You don't have to build everything from scratch. Frameworks have huge communities with pre-built UI component libraries (think Ant Design for React, Element Plus for Vue) that include ready-made modals, form validation, and scrollable console components. Plus, dev tools like React DevTools or Vue DevTools let you inspect state changes in real time, making debugging way faster than spamming console.log in vanilla JS.

• Long-term maintenance is easier
  If you plan to expand your editor later (add plugins, multi-user collaboration, etc.), framework code stays structured and scalable. Vanilla JS can quickly turn into "spaghetti code" as your UI grows, making it hard to debug or add new features months down the line.

Why vanilla JS might cause headaches for your needs #

mrdoob's editor uses vanilla JS because its UI is relatively static and focused on core Three.js operations. But your project needs dynamic, interactive UIs, which expose vanilla JS's weaknesses:

• Manual DOM work is error-prone
  Adding dynamic fields means creating elements, binding events, handling removal, and cleaning up listeners to avoid memory leaks. Tutorial step switching requires manually showing/hiding DOM elements and syncing state—all tasks that are easy to mess up.
• State tracking gets chaotic
  As you add more dynamic elements, you'll end up with dozens of variables tracking UI state (current tutorial step, console log array, field values). Keeping all these in sync with the UI manually is a recipe for bugs.
• Scalability becomes a problem
  Every new feature you add will require writing more custom DOM logic, and your codebase will grow exponentially in complexity.

A middle ground if you're nervous about learning a framework #

If the learning curve feels intimidating, try progressive adoption:

• Start with the most complex part of your UI (like the tutorial wizard or dynamic fields) and build that with a framework, leaving the rest in vanilla JS for now.
• Focus only on the core framework features first: for React, learn function components, useState, and useEffect; for Vue, learn reactive data and single-file components. You don't need to master every advanced feature right away—these basics will cover 90% of your current needs.
• Since you already know JavaScript, picking up these core concepts will be faster than you think—you could be building functional components in a week, then connecting them to your Three.js scene (using useEffect in React to trigger Three.js updates when UI state changes, for example).

Final call #

For your project's needs—complex, dynamic UIs—investing a little time into learning React or Vue will pay off big time in reduced bugs, faster development, and easier maintenance. Vanilla JS works great for simple, static UIs, but your use case is exactly what frameworks were built to solve.
