Overview

Product summary

Review the store description, core capabilities, and common use cases.

Learning to code is hard. Documentation is harder. MDN, W3Schools, 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
