Research direction
Start at the Generics handbook page linked in the issue and review its existing examples and surrounding syntax guidance. Document TypeScript arrow functions with generics, including the trailing-comma form that avoids ambiguity with JSX. Done means the page explains both the syntax and why the trailing comma is useful.

Description
Page URL: https://www.typescriptlang.org/docs/handbook/2/generics.html
Issue: What is the syntax for Typescript arrow functions with generics?
The typescript handbook currently has nothing on arrow functions.
Thomas said this in a comment:
Newer typescript compilers also support trailing comma
const foo = <T,>(x: T) => x;to sidestep the JSX ambiguity
If you add this info in the documentation people won't have to resort to that StackOverflow post to discover these features.
