+# JavaScript
+
+An example which uses JavaScript source files (as opposed to TypeScript) to
+render a component and execute client-side scripts.
+
+This example uses CommonJS to load dependencies, but it should be possible to
+use ESM with the right Node version and configuration. Doing so is not fully
+tested or supported however.
