So it seems like the logical thing to do would be to create a study with better construct validity since it seems you don't think my evidence is any good and you definitely don't have any of your own.

If we're both just throwing around opinions this is no different than arguing tabs vs spaces. I've noticed that Typescript tends to be embraced by teams with lots of subpar enterprise Java developers with limited knowledge of Javascript. The same is also true of Angular, so it's a good fit here, but it's more for mitigating a lack of personal knowledge and organization standards than a general benefit.
