Question: 1 / 400

True or False: One reason to use arrays over objects is that arrays allow easier value access without keys.

True

False

Using arrays can facilitate easier access to values sequentially by their index rather than by a designated key, which is typically used with objects. This characteristic can make arrays advantageous in certain scenarios, especially when dealing with collections of data that have a natural order and do not require the explicit association of named keys.

For example, when iterating over a list of values, accessing elements by their numeric index is often more straightforward and less verbose than dealing with keys in an object. In situations where data is uniform and ordering is important—such as a list of scores or a sequence of tasks—arrays provide a clear advantage in access simplicity.

While the correct choice indicates a misunderstanding of this aspect, it's important to note that the effectiveness of arrays versus objects often depends on the specific use case. If easy access by key is crucial, objects will be more appropriate. However, for scenarios that favor sequential access and indexing, arrays are often the more efficient choice.
