Bridging the Knowledge Gap: Debugging
summary
Argues that bootcamps leave a debugging knowledge gap and gives three concrete practices: binding.pry and print debugging (puts/P, Pry + pry-byebug commands like next/step/continue) to inspect runtime; using the browser Network tab and server logs to spot HTTP 500s and payload mismatches between a Rails API and React frontend; and reproducing failures with tests — example: Puppygotchi bug where a nil database result breaks React, fixed by adding tests and handling the empty query.
