AWK vs JSON: What are the differences?

# Introduction
This Markdown code will provide a comparison between AWK and JSON in terms of key differences.

1. **Data Structure**: AWK is a programming language specifically designed for text processing, allowing users to manipulate and extract data from structured text files. On the other hand, JSON is a lightweight data-interchange format that is used for transmitting data between a server and a web application in a readable format. 
   
2. **Usage**: AWK is often used for tasks like data extraction, reporting, and transforming text-based data, making it useful for processing log files or structured text. In contrast, JSON is primarily used for data communication between servers and web applications, providing a simple format for storing and exchanging data.

3. **Types of Data**: AWK deals with structured text data that can be pattern-matched and processed using its powerful text-processing capabilities. In contrast, JSON deals with unstructured data and is more commonly used for storing complex data structures like arrays and objects in a highly readable format.

4. **File Format**: AWK mainly operates on text files or streams, processing lines of text based on user-defined patterns and actions. JSON, on the other hand, can be stored in files with a .json extension and is often used to represent structured data in a more organized and hierarchical manner.

5. **Syntax**: AWK has a specific syntax with patterns, actions, and variables that allow users to filter and manipulate text data efficiently. JSON, on the other hand, follows a simple key-value pair structure with curly braces and colons to define objects and arrays.

6. **Extensibility**: AWK can be extended using user-defined functions, libraries, and modules to enhance its functionality and flexibility for complex text processing tasks. JSON is more rigid in its structure and does not support extensive modifications beyond its defined key-value pairs and data structures.

In Summary, AWK is tailored for text processing and data extraction from structured text files, while JSON is used for data interchange between servers and web applications in a readable format, differing in terms of data structure, usage, types of data, file format, syntax, and extensibility.
