JSXlike

JSXlike is a JavaScript-based syntax extension designed to simplify user interface construction by allowing HTML-style markup within JavaScript code. It lets developers declare UI structure in a familiar, declarative form while still using JavaScript for data handling and logic.

Code written in JSXlike is transformed by a compiler into ordinary JavaScript calls that create elements or virtual DOM nodes. The transformation targets a render function or a library-provided element factory, allowing different backends beyond a single framework.

Unlike standard JSX, JSXlike implementations are typically designed to be backend-agnostic, enabling integration with various rendering engines or serverside rendering. Attributes and events follow familiar patterns such as setting props with curly-brace expressions and binding event handlers with onX props; spreads are supported to merge attribute collections.

Tooling for JSXlike includes transpilers or plugins for popular tooling ecosystems (for example, Babel or TypeScript plugins) and can be paired with alternative runtimes. Because the syntax is transformed rather than executed, performance depends on the target library rather than the syntax itself.

JSXlike exists primarily in experimental or hobbyist projects and is not part of the official JavaScript specification. It remains a niche approach, with limited ecosystem momentum and potential debugging or tooling challenges when compared to established JSX-based workflows.
