Javascript and other dynamic language like it are very good prototyping languages and for developing a quick mock-up to explore the pros/cons of a potential solution to a problem. But the lack of type checking and proper encapsulation turn into big headaches when scaled to a large app with even a few more junior developers.

Without a compiler/type checker to help spot obvious problems in code runtime exceptions explode. This happens even for senior developers. And the lack of proper encapsulation other than by convention can/does lead to an explosion of the surface area of source code that a dev needs to know and be familiar with in order to refactor and make changes to large codebases which makes for very brittle large apps.

Hence, I look forward to new languages targeting web assembly that will be more amenable to creating/maintaining large scale and long lived apps.
