You can get a ton done in Typescript or Python or Ruby. And in addition to type systems being developed to assure type safety in the most dynamic of languages, you also can write tests and draw on the community knowledge of countless programmers who know your language. Obviously if performance & certain performance first libraries are first priority for you, choose a very computationally efficient lang. But it’s a toothless argument in 2020 to say when following best practices you are inevitably going to write flawed, incorrect code because you’re starting in a dynamic language.
