Full Stack Scala Web Application.
summary
Builds a working full‑stack Scala web app using Scala.js for the frontend, Scala CSS for styling, uPickle for JSON, SBT fastOptJS for live dev and CDN dependencies (jsDelivr) for jQuery/bootstrap. Implements typesafe RPCs that compile away Ajax calls, wires them to a lightweight server router, and shares validation and case classes as shared Scala models between client and server. The demo is a mortgage calculator that returns 360 monthly payments and runs end‑to‑end. fastOptJS dev workflow
