Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser.
Jsonnet is a configuration language that helps app and tool developers generate config data and manage sprawling configurations.

Jsonnet is a powerful, domain-specific configuration language designed for creating and managing complex configuration files. It extends JSON by adding features like variables, functions, and object-oriented programming concepts to eliminate duplication and improve organization. This side-effect-free language supports generating various output formats, including JSON, YAML, and INI, making it suitable for integrating with diverse applications and tools. Jsonnet is particularly useful in environments like Kubernetes, Terraform, and Packer, where managing configurations efficiently is crucial. It offers features like a reformatter, linter, and editor integrations to streamline the development workflow. Primarily aimed at app and tool developers, Jsonnet provides a flexible and maintainable approach to handling configuration data.

Jsonnet allows users to define configuration objects with inheritance and polymorphism, reducing redundancy and promoting code reuse. Objects can inherit properties and methods from parent objects, and override them as needed.
Jsonnet supports defining functions with parameters and local variables. This enables creating reusable configuration templates and performing calculations within the configuration.
Jsonnet can generate output in various formats, including JSON, YAML, and INI. Users can define custom output formats using string interpolation and built-in functions.
Jsonnet is a purely functional language, meaning that evaluating a Jsonnet expression always produces the same result and has no side effects. This ensures predictable and reliable configuration generation.
Jsonnet includes a rich standard library with functions for manipulating strings, numbers, and data structures. Users can also define custom functions and import them into their Jsonnet files.
Install Jsonnet from the official website or using a package manager.
Familiarize yourself with the Jsonnet syntax by reviewing the language reference.
Create a simple Jsonnet file (e.g., `example.jsonnet`) with basic JSON structures.
Use the `jsonnet` command-line tool to evaluate the Jsonnet file and generate JSON output.
Experiment with variables and functions to define reusable configuration components.
Integrate Jsonnet with your existing applications or infrastructure management tools.
Explore advanced features like object-orientation and custom output formats for more complex configurations.
