What does the "Where" query do?

The "Where" query is designed to retrieve all members of an array that meet a specified condition. This means that when using a "Where" query, you can filter the elements in the array based on certain criteria. For example, if you have an array of customer records and you want to obtain only those customers from a particular city, the "Where" query will allow you to specify that condition and return all matching elements.

This filtering capability is crucial in data analysis and manipulation, especially when dealing with large datasets, as it helps in efficiently narrowing down the information required for further processing or analysis. In contrast to the other options, which either imply specific actions like counting or evaluating single elements, the "Where" query focuses on condition-based retrieval, making it a powerful tool for managing arrays.
