Why json over xml?

JSON is preferred over XML because it is significantly more lightweight and easier to read. JSON's concise syntax reduces file sizes by 30-50% compared to XML, resulting in faster data transmission and lower bandwidth costs. Parsing JSON is faster and requires less memory than XML processing. JSON integrates seamlessly with JavaScript, the dominant web programming language, without requiring additional libraries. The structure of JSON naturally maps to objects and arrays in most programming languages, simplifying data manipulation. XML's verbose closing tags, attributes, and namespaces add unnecessary complexity for simple data exchange. JSON is easier for developers to write, read, and debug. Modern web APIs almost universally choose JSON for these practical advantages in performance and developer experience.
