  description

  Learning to code is hard. Documentation is harder. MDN, DevDocs and javascript.info are incredible resources — but they treat a beginner and a senior developer exactly the same way. 
  Every section looks equally important. Nothing tells you where to start.
  Dev to Hero fixes that.
  
  It automatically color-codes every section of a documentation page based on its difficulty level:
  🟢 Beginner — read this now
  🟡 Intermediate — come back after the basics
  🔴 Advanced — no need to stress about this yet
  
  But it goes much further than just color badges:
  
  📌 Smart prerequisites — each section tells you exactly what you need to know first, sorted by learning order and split between required (★) and optional (○) concepts. Each prerequisite links directly to the relevant doc page. Click once to mark as approached, click twice to mark as mastered — synced across all supported sites and sessions.
  
  📊 Page summary — see at a glance how many beginner, intermediate and advanced sections a page contains, which prerequisites you still need to master, plus an estimated reading time.
  
  ☐ Track your reading — mark sections as read and watch your progress update in real time.
  
  🎯 Focus mode — show or hide beginner, intermediate and advanced sections independently so you can focus on exactly what's relevant to your level.
  
  📋 Export your study plan — download a clean, structured study plan showing all sections by level, your read status, and prerequisites still to cover.
  
  💡 Next reading suggestions — at the end of every page, Dev to Hero suggests what to read next based on your knowledge.
  
  ✎ Report incorrect badges — votes are currently local to your browser. Shared community voting may be added in a future update.
  
  ⌨️ Keyboard shortcut — toggle the extension on/off with Alt+Shift+M.
  
  Currently supported sites:
  
  MDN Web Docs (HTML EN, CSS EN, JavaScript EN), DevDocs (HTML EN, CSS EN, JavaScript EN), javascript.info (EN & FR)
  4 690 pages covered — with more added regularly.
  
  Coming soon: MDN French, additional MDN dev languages, CSS in French, HTML in French, Python, TypeScript and more.
