Adventures in Vibe Coding – Really, Really Big Numbers

/ / No Comments
I continue to be really against the term ‘vibe coding’, but also continue to be fascinated by the idea of working with GenAI to help craft/enhance applications in an iterative, conversation-based manner. Ashley Willis recently released an incredibly well done post on the topic, "What Even Is Vibe Coding?", where she goes into detail on her take on the term and what it means for the industry.

The Number primitive has a toLocaleString method to do the basic formatting for you: const price = 16601.91; // Basic decimal format, no providing locale // Uses locale provided by browser since none defined price.toLocaleString(); // "16,601.91" // Provide a specific locale price.toLocaleString('de-DE'); // "16.601,91" // Formatting... more →
