“LLM”s are a constantly updating product, the new DeepSeek coder model with GPT-o1 like reasoning and chain of thought just came out, and its a lot superior than LLM models from even 1 month ago, especially when trained on internal docs, and files, and synthetic LLM generated metadata on those files, all accessible under an effective hybrid search engine.
It’s perfectly usable with Dynamic languages like JS and Python, and perfectly doable to write bug free effective code, is one is restrained and thoughtful in its use, which builds up as muscle memory over time anyways.
Especially if one considers linters and type hints enabled in js (as ts) and python type hints, then it becomes even more doable, if you’re insistent on static typed only language code with LLM.
