Prefer clear, semantic code

Write code that’s easy to read and matches intent (mutability, string composition, UI semantics), and remove obvious clutter.

Apply these rules:

1) Avoid reassignable variables

• Prefer const when a value isn’t reassigned.

  const repository = curriculumLocale === 'english'
  ? 'freeCodeCamp'
  : 'i18n-curriculum';
  

2) Build static paths/strings directly

• For URL/path-like strings made of known segments, prefer array joining (or a single template literal) over nested join(...)/extra indirection.

  const challengesFolder = ['blob', 'main', 'curriculum', 'challenges'].join('/');
  const gitPath = [repository, challengesFolder, curriculumLocale, 'blocks', block, `${challengeId}.md'].join('/');
  gitURL.pathname = gitURL.pathname + gitPath;
  

3) Don’t add redundant conditionals when UI state already guarantees behavior

• If a control is disabled, the handler usually doesn’t need guarding. ```tsx

<Button disabled={isClassroomAccount} onClick={updateIsClassroomAccount} /> ```

4) Render links as links; actions as buttons

• If the user is navigating to/copying/opening a URL, use a link element/component. Avoid “button that opens a new tab” when a link is available—this improves accessibility and expected browser features.

5) Remove duplicate/unused imports

• Keep imports unique and ensure every import is used (e.g., don’t import the same symbol in multiple places).
