No but they help. You can find figures of a 15%-38% reduction in bugs for TypeScript versus JavaScript. So that does not consider the additional effect of strong versus weak typing.

I'm in agreement with you about Typescript, but JS has other deficiencies that contribute to typing issues.

Anecdotally, I'm frequently enough bitten by type issues in JavaScript, but I can't recall very many in Python. Certainly not 15-38%, perhaps 1%.

Which furthers my point (for my set of circumstances): I find the majority of my bugs when I'm writing tests.
