I've never seen a number far outside of the 15-30% range.

In my experience, most bugs are operator error. Developers didn't code for branching paths that should've been accounted for, etc.

Personally, I'm a fan of TypeScript. Just don't expect to remove the majority of your bugs via its usage. The old "no silver bullet" adage.

How is JavaScript worth it if it typically adds 15-30% more bugs? That’s an enormous figure.
Well, it runs everywhere, for one. That's an attractive quality to a language.
