 The key idea is to show how you can currently **call Java methods directly from JavaScript** without relying on the `main()` method.
-This demo exposes a simple Java `add(int a, int b)` method to the global JavaScript scope using the `@JS` annotation from the [Annotation Interface](https://www.graalvm.org/sdk/javadoc/org/graalvm/webimage/api/JS.html).

 ### Conclusion
 
 The focus of this demo is to demonstrate direct interaction between Java and JavaScript in the browser via WebAssembly.
-Note that the [GraalVM Web Image API](https://www.graalvm.org/sdk/javadoc/org/graalvm/webimage/api/JS.html) is still under active development, there will be better ways to export Java methods to JavaScript.
