What is TSRX?: What JSX would look like if it were designed today

JSX has been a mainstay in React's templating syntax since 2013, often requiring developers to adopt specific patterns to manage conditionals, lists, and styles. TSRX, a TypeScript-compatible extension developed by Dominic Gannaway, seeks to address these challenges by introducing first-class control flow constructs like @if, @for, and @switch, and allowing scoped styles within component templates. Unlike JSX, which relies heavily on function calls and expression slots, TSRX provides a more structured template design, enabling clearer delineation between setup and output in component code. The compiler processes TSRX into an AST, allowing framework-specific plugins to produce optimized outputs for React and other frameworks. While not a new framework or a proposed JavaScript standard, TSRX is a language extension that React developers can currently test and evaluate for its potential to simplify component structuring and styling. However, as an emerging tool with evolving specifications, teams are advised to experiment with it cautiously and monitor its development before considering a full transition.
