It helps you understand the platform, not just the API. You learn patterns and conventions, can debug harder problems at the platform level, can contribute to open source, and see how real production software is built. It is the fastest path from junior to senior.
When something breaks at the platform level, not just in your code, reading the source is the only way to understand why. This is a senior-level debugging skill that tutorials and docs cannot teach, since you see the actual implementation.
Patterns for error handling, testing, module structure, and API design. Large codebases like Node.js use consistent patterns, and reading them teaches you these patterns, which you can apply to your own projects.
