React vs Angular: how a library can compete with a framework

Every React developer has an opportunity to work with a special HTML-like syntax JSX to render components. Unfortunately, both TypeScript in Angular and React cannot do without JSX.

It's also necessary to proofread your copies with other people. I fail to understand the point of this section no matter how hard I try. React works just fine with TS & JSX and without both. What were you trying to state?
