Which methods are considered better than '.Count' for checking results without fetching data? Choose two.

Using methods that do not require fetching all the data can significantly improve performance, especially when you're only interested in determining the presence of data rather than retrieving it.

The method 'isEmpty' is particularly efficient for quickly determining whether a collection or query result contains any items without needing to retrieve the entire dataset. If the result set is empty, it returns true immediately, without any data fetching overhead, making it a best practice in scenarios where you just need a simple check for existence.

The method 'fetchCount' is also advantageous because it directly retrieves the count of results from the database without fetching the complete data. This is especially useful in a scenario where only the count is needed for business logic or user interface rendering, optimizing performance by minimizing data transfer.

Other methods like 'getCountLimitedBy(x)' and 'checkExists' can also be useful in different contexts. 'getCountLimitedBy(x)' allows you to check the count of results up to a limit, which can be resource-intensive depending on the size of the data fetched if implemented inefficiently. While 'checkExists' similarly checks for existence, it may not be as optimized as 'isEmpty' for use cases specifically aimed at assessing the presence of data efficiently.
