Error Handling Issue
The startObserver method sets up an observer with the inView function but does not include any error handling mechanisms. This could lead to unhandled exceptions if the inView function encounters errors, such as invalid arguments or issues with the browser's IntersectionObserver.
Recommendation:
Implement try-catch blocks around the inView function call to handle potential exceptions gracefully. This will improve the robustness of the observer setup and prevent the application from crashing due to unhandled errors.

Performance Optimization
The update method uses a combination of .some() and a custom function hasViewportOptionChanged to check if observer options have changed, which might be inefficient if the properties list is large or changes infrequently.
Recommendation:
Consider optimizing the check by caching previous properties and comparing directly or using a more efficient method to detect changes. This could reduce the overhead of function calls and iterations, improving the performance of the update method.
