What common features can be identified in data formats JSON, XML, and YML?

JSON, XML, and YAML are data formats used for storing and transmitting structured information. Common features of these formats:

• Text-based format: all three formats represent data in a readable text form.
• Structured: they allow describing complex data structures — objects, arrays, nested elements.
• Versatility: used in various programming languages and systems for data exchange.
• Support serialization and deserialization: easily converted to and from programming objects.
• Human-readable: although the degree of readability varies, all three formats are designed to be understandable by humans.

Example: all three can describe a list of users with their names and ages, but the syntax will differ.
