But each time i re-read this post, the cohesive point that pops out most is that this post is basically a Donald Trump speech about Typescript.
The claim is that it's bigger, it's better, and everyone else is a bit sad. It disingenuously claims that it's not about about competition and then literally ends with "Typescript Won".
So, lemme offer some rhetorical advice:
1) pick to a POV & stick to it. It's a competition or it's not. You either think it's worth highlighting how much better Typescript is over other technologies, or you don't.
2) Most of the points made in the post aren't assertions about the benefits of Typescript or the decisions it makes. Not everyone agrees that the existence of a static type checker is an unqualified benefit (and there are many dimensions to that conversation). If you want to make the assertion that Typescript makes your life easier/better because it has a type checker, assert the benefits of having a type checker (and the decision making for AngularJS's adoption of Typescript on the basis of having a type checker could use a citation).
3) Related to 1., this post comes off as MEGA passive-aggressive because you keep on mentioning how much you also love other technologies at the same time talking about how they are inferior to Typescript on a variety of shifting bases. Because of that you're not telling a cohesive story about Typescript. You're just talking about how you think other technologies are bad.
