About:
Jsonnet is a data templating language that allows users to generate JSON or YAML configuration files dynamically. It enables the composition and modification of configuration data using variables, functions, and imports, significantly reducing duplication and complexity in large infrastructure definitions.

Key Features:

Purely functional language with lazy evaluation
Standard library for manipulating JSON data structures
Imports for modularizing large configurations
Output is valid JSON or YAML

Use Cases:

Generating Kubernetes manifests
Managing complex Infrastructure as Code configurations
Abstracting repetitive JSON/YAML data

Alternatives:

YAML – Jsonnet offers programmability and DRY principles compared to static YAML
HCL – Jsonnet is JSON-compatible and purely functional, unlike HCL
