JSON Essentials

Description:

This 2 day training provides an in-depth introduction to JSON (JavaScript Object Notation), the most commonly used data interchange format in web applications and APIs. Participants will learn how JSON works, how to create and parse JSON data, and how to integrate JSON with different programming environments. The course covers basic syntax, data structures, and best practices for working with JSON in real-world applications.

By the end of the training, participants will have the skills needed to effectively use JSON in data-driven web and mobile applications, as well as an understanding of JSON in the context of RESTful APIs and data manipulation.

Duration: 2 Days

Course Code: BDT373

Learning Objectives:

After this training, you will be able to:

• Understand the structure and syntax of JSON.
• Create and manipulate JSON objects and arrays.
• Convert data between JSON and various programming languages (e.g., JavaScript, Python).
• Utilize JSON in AJAX and API
• Validate and format JSON data.
• Implement JSON in web applications and server-side
• Understand best practices for using JSON in APIs and data storage.

• Basic understanding of programming concepts
• Familiarity with web technologies (HTML, JavaScript) is beneficial but not mandatory

• This training is designed for developers, web designers, data analysts, and IT professionals who want to learn the fundamentals of JSON and how to utilize it in data interchange, web development, and application programming. It is also suitable for individuals interested in working with APIs and understanding how modern data is transferred between systems.
