These other actions are all safe for JS frameworks.

 ## TypeScript Usage in JS Frameworks
 
 Many JS frameworks, such as Svelte and React, often define their own "Element Namespaces". Because of this, most frameworks are not able (on their own) to recognize the correct attributes, properties, and event listeners that belong to the Custom Elements which you use. Thankfully, our library ships with TypeScript types that tell the various JS Frameworks about the existence and shape of our Custom Elements. To define _all_ of our library's Custom Elements within a Framework's "Element Namespace", simply import the appropriate type definition file:
