jk
Configuration as Code with ECMAScript
jk is pre-1.0, and as such, features, commands, and APIs inevitably will change. jk is a data templating tool designed to help write structured configuration files. The main idea behind jk is to use a general-purpose language for this task. They offer mature tooling, great runtimes, a well-established ecosystem, and many learning resources. jk uses Javascript and a runtime tailored for configuration.
