In the realm of data interchange formats, JSON, XML, and YAML are three commonly used options. Each format has its strengths and weaknesses, making them suitable for different scenarios. Let's delve into a comparison of JSON with XML and YAML to understand their differences and when to use each.

JSON (JavaScript Object Notation)

JSON, a lightweight data interchange format, is widely used due to its simplicity and readability. It is based on key-value pairs and arrays, making it easy for both humans and machines to understand. Here's a simple example of JSON:

{
  "name": "John Doe",
  "age": 30,
  "isStudent": true,
  "courses": ["Math", "Science"]
}

XML (eXtensible Markup Language)

XML, known for its hierarchical structure, is often used in web services and configuration files. While more verbose compared to JSON, XML offers strong support for validation and transformation. Here's how the same data looks in XML:

<person>
  <name>John Doe</name>
  <age>30</age>
  <isStudent>true</isStudent>
  <courses>
    <course>Math</course>…
