I have a lot of sympathy for your point of view. Though have a look at Rust: it's generally considered much more typesafe than both JavaScript and C++, but it also has (some) dark corners of undefined behaviour with approximately all the same baggage as C++.

See also https://news.ycombinator.com/item?id=8206562 for a different point of view: dynamically typed languages are equivalent to statically typed languages with just a single static type.
