State of HTML 2023

Componentes Web

Despite JavaScript frameworks being used more widely than ever, there is still a need for native solutions. Yet Web Components currently fall short of addressing developer pain points effectively, with Web Components APIs and especially Shadow DOM dominating the top 10 of worst experiences across all HTML-related technologies.

This indicates that there is still significant work to be done before they can truly enhance HTML's extensibility and become a strong alternative to framework components. However, the ongoing activity in this area leaves me hopeful.
