RESTful JSON API features and specs

• Interoperability
  JSON is language-agnostic, enabling data exchange between applications written in different programming languages.
• Readability
  JSON's simple syntax makes it easy for humans to read and understand, facilitating easier debugging and data inspection.
• Lightweight
  JSON's lightweight structure results in reduced network bandwidth usage, making it suitable for mobile and web applications.
• Widespread Adoption
  JSON's popularity ensures robust library support across almost all programming languages, easing development and integration processes.
• Ease of Use with JavaScript
  JSON is natively supported by JavaScript, making it ideal for web development, as it eliminates the need for data transformation.

Possible disadvantages of RESTful JSON API

• Limited Data Types
  JSON supports a limited set of data types, which might not be sufficient for complex data structures, requiring additional parsing.
• Lack of Schema
  JSON does not mandate a data schema, increasing the risk of inconsistent data structures unless explicitly enforced.
• Security Vulnerabilities
  JSON is susceptible to security vulnerabilities such as JSON injection, requiring additional precautions during implementation.
• Verbosity for Large Data
  For extremely large datasets, JSON may become verbose and harder to manage in terms of both size and readability.
• No Built-in Date Type
  JSON lacks a built-in date type, leading to inconsistencies in date handling across different systems and libraries.
