Highlighting common pitfalls and best practices

Here are some common pitfalls or scenarios to avoid when using combineLatest in RxJS:

Unnecessary subscriptions

combineLatest subscribes to all provided Observables automatically. Make sure you unsubscribe from the returned subscription when you no longer need the combined values, especially for long-running or infinite Observables. This prevents memory leaks and unnecessary processing.

Missing or incomplete values

combineLatest only emits a value when all its source Observables have emitted at least one value. If any Observable completes or throws an error before all have emitted, combineLatest will also complete or error out, respectively. Consider using the withLatestFrom operator if you only need the latest value from one Observable combined with the entire emission history from another.
