The article gives 8 examples of transpiled languages, 4 dynamically typed and 4 statically typed. There's no real preference for static typing, and in fact I'm a big fan of dynamic typing.

However, there's a difference between a strongly typed dynamic language and a weakly typed dynamic language. JavaScript is an example of the latter and it's done very badly (eg, inconsistent semantics). The lack of discipline makes it difficult to write safe, reliable software. Thus, JavaScript is ill-suited for serious software engineering.
