Not necessarily - bunch of languages have adopted JSX with slightly or substantially different component semantics from React (for example Vue, Solid, Forgo, Crank). A Crank component (which is an async generator) feels very different from a React component. Likewise for a Forgo component, which uses closures for state and doesn't have automatic rerenders. Solid doesn't have components in the traditional sense at all. Although the syntax they use for representing HTML is the same, the rest of the framework can have arbitrary design.
