2. Define the function you want to convert to an observable using bindCallback. The function should have a callback as its last argument:

index.ts
function myFunction(arg1: any, arg2: any, callback: (result: any) => void) {
  // function logic here
}

3. Use the bindCallback function to create an observable from your function:

index.ts
const myObservable = bindCallback(myFunction);

2 lines

4. Subscribe to the observable to access the results of your function:

index.ts
myObservable('arg1 value', 'arg2 value').subscribe(result => {
  console.log(result);
}, error => {
  console.error(error);
});

In this example, the myObservable variable is an observable that will emit a single value when the myFunction function completes. The arguments passed to myObservable will be passed on to myFunction. The subscribe method is used to handle the emitted value and any errors that occur during the execution of myFunction.
