call a kotlin method using a native function invocation in javascript

To call a Kotlin method using native function invocation in JavaScript, you need to follow these steps:

1. Create a Kotlin function, annotate it with the @JsName annotation, and declare it as external to indicate that it will be implemented in JavaScript:

import kotlin.js.JsName

@JsName("myKotlinFunction")
external fun myKotlinFunction(param: Any): Any
100 chars
5 lines

2. Compile the Kotlin code to JavaScript using the kotlin2js compiler:

kotlinc myfile.kt -output myfile.js
36 chars
2 lines

3. In your JavaScript code, load the generated JavaScript file and invoke the Kotlin function using the name specified in the @JsName annotation:

index.tsx
const result = myKotlinFunction("my parameter");
49 chars
2 lines

Note: The name specified in the @JsName annotation must match the name used to call the function in JavaScript.

That's it! Now you can call your Kotlin functions from your JavaScript code using native function invocation.
