JSON

This two day ABIS course teaches the practical skills for working with JSON.

JSON (JavaScript Object Notation) has become the standard format for data exchange in modern applications. Its simplicity and readability make it essential for developers working with web services, APIs, and data-driven systems.

This course introduces the core aspects of JSON: its syntax, the use of JSON Schema for validation, methods for
searching and transforming JSON, and how JSON is applied in APIs and JavaScript. Together, these topics provide both the fundamentals and practical skills needed to work effectively with JSON in real-world projects.

In this course, you will learn

  • to create and to interpret JSON documents
  • to impose structure via JSON schemas
  • to search and transform JSON documents
  • how JSON is used in APIs
