not saying it's enough to get bloomberg first co-op but it's definitely pretty good. a lot of us fail to take a step back and realize what goes into making a simple but polished CRUD app

understanding backend/frontend interaction, React basics like state, Node basics like npm/express, JavaScript concepts like promises and ES6 features, what AJAX calls are, deploying this site onto AWS, setting up a CDN, setting DNS records/CNAME for domain name, learning how HTTP requests work, how CORS works for the API calls, calling external APIs, understanding how to work with JSON, maybe it's version controlled using git/mercurial, used a linter, has a responsive site design, properly documented, has logging, smoke tests, unit tests, hooked up to a simple CI build system, displays currencies using a visualization library like D3, etc.
