Many Javascript people hate Typescript. Yet is is so similar to C# that solutions using Asp.Net Core for Backend essentially have an isomorphic development environment.

Yes, Typescript is an excellent tool especially for Intellisense. This gives instant API discoverability. It's everything Javascript plus a lot more.

How is TypeScript code more readable than plain JS? I think it makes your code more bloated and puts less focus on the actual logic, more on just type checking. However I've not done so much in TypeScrip yet!

It helps you structure your code better by giving you better tools. OOP, SOLID, many language features vanilla JS is missing like decorators, optional chaining, nullish coalescing and many other features. IntelliSense/auto-completion makes you more productive and helps you avoid typos.

Optional chaining and nullish coalescing are built into JS

...but not supported by all browsers.

Dear vanilla JavaScript users, which version do you use? Transpiler?

TypeScript is both helpful and fake.

It doesn't provide run type checking. And sometimes typings are wrong!

Most famously, Array[n+1] and Record<string, any>['non-key'].

Yes, I prefer Typescript, by thousands of times. But, I have also seen weird bug produced a couple times because TS can't really predict everything someone might do with objects.
