One is procedural (JavaScript), the other is declarative (HCL).

Both are (or at least were originally) “crippled” compared to “real” languages.

Both grew immensely each eventually escaping their single-vendor origins.

I don't think that this is a true comparison. JavaScript was limited mostly by its sandboxing, not what you could write in it. You can't really compare that to what HCL is and does.
