Feedback and the REPL

on YouTube ↗32m

" summary

Argues that eliminating build/reload delays gives much faster feedback and fewer debugging rounds, then demos a working workflow: a VS Code plugin sends selected code to a browser REPL so modules can be imported, edited and evaluated live. Shows Replete (open source on GitHub) creating a Vue component end-to-end — spec, demo, implementation — and it runs in the page with event handlers. Calls this REPL-driven development and labels the file a whole-module.
