YOUR DICTIONARY FOR ENGLISH STUDENTS

Hi there,

This is a very good solution design-wise - the mockups match nicely. There are some important things to note however:

• You should use React's native state management to handle the logic of the application. I haven't seen all the code, but just looking at the ThemeSwitcher, you're directly modifying the DOM with document.documentElement.dataset.theme. This is basically vanilla JS, which isn't exactly wrong, but it isn't leveraging the purpose of React.

• Essentially you should be using hooks like useState to set a state variable and update it's value via the setter function, and useEffect to handle the color preference detection, as well as an event listener to detect changes in the color scheme preference and update the UI based on the user's preferences and actions (which updates the state accordingly). This will lead to a more robust, stable component. If you haven't used native state management in React before, it would be good to review/look into this.

• With regards to your question - Netlify or Vercel are ideal for front-end, client side applications, (vanilla, React, Angular etc.) I use Vercel, which automatically detects the Vite framework and builds your project each time you push your changes to the main branch (without needing to run a build script beforehand.) They handle caching, performance and overall stability very well and Vercel has CI/CD to manage deployments for both main and other branches, watching for errors during build time. You can set an account up with GitHub and deploy your projects from selecting your repos.

Hope this helps!
