What does the key-value pair structure in JSON allow for?

The key-value pair structure in JSON allows for simplified identification of data attributes. This format consists of pairs where each key acts as a unique identifier that associates with a corresponding value. By organizing data this way, it becomes intuitive to access specific pieces of information directly using the keys. For example, in a JSON object representing a person, you might have keys like "name," "age," and "email," making it straightforward to retrieve each attribute.

Although organization in rows and columns pertains to tabular data formats like SQL databases and spreadsheets, it doesn’t correspond to the flexible structure offered by JSON. Similarly, clear representation of individual records, while a valid point regarding data structure, doesn’t capture the essence of how key-value pairs function. Lastly, while easy manipulation of large datasets using indexes is a characteristic of certain database management systems, JSON itself does not inherently provide this capability since it is designed primarily for data interchange and not optimized for large dataset manipulation in the same way relational databases might be.
