About:
Jr is a command-line interface tool designed to generate high-quality, realistic random data for development and testing. It allows users to create complex data structures, including JSON and CSV formats, using simple templates. This streamlines the process of populating databases or mocking APIs with diverse datasets.

Key Features:

Template-based data generation
Support for JSON and CSV outputs
Built-in library of data types (names, addresses, etc.)
Customizable data schemas

Use Cases:

Generating mock data for database seeding
Creating fake API responses for frontend development
Producing sample datasets for software testing

Alternatives:

Faker – Jr is a standalone CLI, whereas Faker is primarily a library for languages like Python or JS.
jq – Jr generates data, while jq is used for parsing and querying existing JSON data.
