> Honest question, why not just use… JavaScript? I get that this is scoped to only templating json, but the syntax is already diverging pretty heavily from actual JavaScript, while also trying to pretend to be similar? Jsonnet's stated aim is to be a superset of JSON rather than something similar to JavaScript. Having used Jsonnet for a while, it's nice in that it makes it relatively easy to take existing JSON and incrementally turn it into templates. You wind up with the ability to create some nice abstractions for elements of JSON. The close coupling between the syntax of the emitted output and the Jsonnet script itself makes it far easier to write a correct template than when using something like gotmpl to create Yaml in a Helm chart. Whether or not this is worth another language is a judgement call, but it's not that hard to learn or work with, so I've tended to find Jsonnet a nice tool to have around.
