- teach web components in a frontend course
When to choose
- you are learning or teaching web components from MDN docs
- you want small, clear reference implementations of custom element patterns
- you need runnable demos of shadow DOM, slots, and lifecycle callbacks
When to avoid
- you need a production-ready web component library or framework
- you want polished, feature-complete UI components for an app
- you need a build system or tooling around web components
