How is data typically structured in a JSON file?

Data in a JSON file is primarily structured as key-value pairs. This format allows for easy readability and access to information, which is one of the reasons JSON has become a popular data interchange format.

In a JSON object, data is stored in a way that each key is paired with a corresponding value. This means you can easily look up information by referencing the key, such as "name": "John" or "age": 30. The value associated with each key can be a string, number, array, boolean, or even another JSON object, which adds to the flexibility and usability of the format.

While JSON can also incorporate arrays and objects, the fundamental structure includes these key-value pairs as the primary means of organizing data. This makes it distinct from concepts such as nested loops, which are not a part of JSON's structure, being more aligned with control flow in programming languages. Thus, focusing on key-value pairs is essential to understanding how JSON represents data effectively.
