JSON for beginners.

Learn JSON and JSON APIs: A Beginner-Friendly Course

This course is designed for anyone looking to understand JSON (JavaScript Object Notation), whether you have prior experience or are starting from scratch. You'll gain practical knowledge of JSON APIs and how to effectively use them in your projects.

What is JSON?

JSON is a widely used standard for representing data. It's a lightweight format that's easy for humans to read and write, and easily parsed by machines. JSON is based on a subset of the JavaScript programming language, making it a natural choice for web development. We'll cover the fundamental syntax of JSON and explore its advantages and purpose in web APIs.

Understanding JSON Data Types

This course dives into the various data types in JSON. You'll learn how to represent data effectively using:

• Strings: Textual data.
• Numbers: Numeric values.
• Objects: Collections of key-value pairs.
• Arrays: Ordered lists of values.
• Booleans: True/False values.
• Null: Represents the absence of a value.

JSON vs. XML: Choosing the Right Format

We'll compare JSON with XML (Extensible Markup Language), another common format for web APIs. You'll discover the key differences and understand why JSON is often preferred over XML in modern web development due to its simplicity and efficiency.

Hands-on Practice with Public JSON APIs

Get practical experience by browsing public JSON APIs. We'll explore readily available APIs that you can use for practice and non-profit projects. This hands-on approach will solidify your understanding of JSON integration.

Calling JSON APIs with JavaScript

Learn how to call a JSON API using JavaScript. We'll demonstrate how to use XMLHttpRequest (Ajax) to retrieve data from a public API, specifically focusing on a practical example: converting currency from USD to INR. You'll gain proficiency in the JavaScript syntax for XMLHttpRequest, enabling you to fetch and utilize data from external sources in your web applications.

Prerequisites:

A basic understanding of HTML/CSS and JavaScript is recommended.
