OVERWHELMED AT NEW FAANG JOB (REDDIT THREAD)

Summary from the TLDR Web Dev newsletter

This Reddit user is overwhelmed by the immense size and complexity of the codebase at their new FAANG job, which involves over 8 million lines of legacy code with lost knowledge. Their task is to replace an outdated build process with a new one using currently unsupported technologies. Comments suggest that the author should prioritize understanding the existing codebase, document their findings, build relationships with colleagues who possess relevant knowledge, and write test cases for legacy code before starting to make changes.
