In my experience, most of the NodeJS shops do this. Because, LLMs on the surface seemingly are good at giving you a quick solution for JS code. Whether it's a real solution or patchwork is up for debate, but, for most mid-level to junior devs, it's good enough to get the job done. Now, multiply this workflow 10x for 10 employees. That's how you end up with a complete rewrite and hiring a senior consultant.
