You may not realise this, but TS is just JS + Types.
The root comment appreciates the framework, and shares their unwillingness to write JavaScript and HTML. The reply to that comment asks why don't they try TypeScript.
I think that reply is absurd because asking someone to write TypeScript when they dislike JavaScript in the first place is absurd.
I know and realise the fact that JS+Types is way better than plain JS, and infact I write TypeScript on everyday basis.
I don't think it's absurd to ask someone to try Typescript first before jumping through hoops just to make Python run on the web, which certainly brings a lot of problems of its own. You do have to actually try it to see how it's a completely different experience, even if the types are just bolted on.
