Is YAML and XML same?
XML supports complex data types such as charts, images, and other non-primitive data types. JSON supports only strings, numbers, arrays, Boolean, and objects. YAML, on the other hand, supports complex data types such as date and time stamps, sequences, nested and recursive values, and primitive data types.
Is YAML similar to XML?
YAML uses a different structure and syntax from XML, which makes it human-readable, not machine-readable. The primary function of YAML is data transmission rather than data formatting. Its syntax is strict but simple.

Is C# a declarative language?
C# is imperative. Declarative programming is a programming paradigm … that expresses the logic of a computation without describing its control flow. Imperative programming is a programming paradigm that uses statements that change a program's state. Declarative Programming is like asking your friend to fix your car.
Is C++ a declarative language?

Because it is declarative, the machine can be visualized. If using TypeScript, the compiler checks that only valid state transitions are performed.
Is Kotlin imperative or declarative?
In declarative programming, especially in a Kotlin programs, we use lambda expressions to simplify our code by simply describing what to be done as opposed to imperative programming which focuses on providing a sequence of steps to get the required outcome which can also be associated with functional programming.
Why JSON is better than XML?
One of the most significant advantages of using JSON is that the file size is smaller; thus, transferring data is faster than XML. Moreover, since JSON is compact and very easy to read, the files look cleaner and more organized without empty tags and data.
Is XML the same as API?
An API is a more robust and powerful method than XML and you can use it to create bi-directional integrations. It removes the need to synchronize data across the two applications (as with XML) because all attributes are available to query.

Is JSON similar to XML?
JSON is Unlike XML Because
The biggest difference is: XML has to be parsed with an XML parser. JSON can be parsed by a standard JavaScript function.
Is XML more expressive than JSON?
XML: Requires explicit type definitions and supports complex data structures. It can represent data in a more structured way. JSON: Supports basic data types such as strings, numbers, arrays, and objects. While it is less expressive than XML, it is often more straightforward for common use cases.
