If you had to, you could go from typescript to JavaScript overnight in a large project, whereas no similar escape hatch exists for C#.

As for the frontend, you have to have so JavaScript somewhere, it’s unavoidable, so typescript is just a way to make the inevitable more palatable.

How is the first paragraph significant or even relevant? What scenario are you contemplating to hedge against?

And there are other frontend options that go without any JS on your side, so it’s quite avoidable. In most cases it’s impractical to avoid JS for the browser target. But the browser is not the only UI target for many apps.
