What are some common challenges faced by Elm programmers when integrating with existing JavaScript applications?

Elm programmers often encounter challenges when integrating Elm components into larger JavaScript codebases, particularly with managing interop between Elm and JavaScript. Since Elm enforces strict type safety and has its own architecture, coordinating data flow and events between Elm and JavaScript (using ports) can require careful planning. Additionally, ensuring smooth communication and maintaining clear boundaries between Elm-managed and JavaScript-managed state are important to avoid complexity and bugs. Collaboration with frontend teams familiar with JavaScript frameworks is common, and understanding both environments helps in facilitating successful integration.
