-:::danger TypeScript and TSX are different.
-TypeScript is a typed JavaScript extension and TSX is a further extension that allows JSX elements.

+:::danger TSX and TypeScript are different.
+TSX differs from TypeScript because it is an extension of the latter that supports JSX elements.
+They need distinct parsers because of [conflicting syntax](https://www.typescriptlang.org/docs/handbook/jsx.html#the-as-operator).
 
 In order to reduce rule duplication, you can use the [`languageGlobs`](/reference/sgconfig.html#languageglobs) option to force ast-grep to use parse `.ts` files as TSX.
