The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Please put units in names
For this purpose I'm pretty ok with Hungarian notation. Haven't found a nice type based solution yet. I tried to roll my own, but looking back I'm not really satisfied with it. Besides, I'm no longer doing anything with physics calculations.

Type-Safe Printf() in TypeScript
Curious what your issue was with duck-typing. Were you effectively looking to create ADTs that are required to go through a specific step-by-step process, not simply 'look like' the thing that was expected?
If so, you might be interested in [newtype-ts].

Is there a language with custom type support (value objects)?

I too prefer no classes
You don't need classes for nominal types: https://github.com/gcanti/newtype-ts

When do you find Branding to be useful?
Creating newtypes (via newtype-ts) for fractions and percentages is worthwhile if you're very concerned about correctness, though it's unfortunate that absent typeclasses they're not terribly ergonomic.

I haven't used this library in particular or this one, but bless the authors and all the others for trying to make it happen… the project I'm now leading uses strongly typed strings for different component addresses, and it saves me to constantly look up the documentation what the functions need – it's beautiful.

Type that's NOT another type?
A "nominal" solution with no runtime overhead can be provided by branded types, other words for this are "opaque types" or "newtypes". Some libraries like newtype-ts exist to help with the construction of these. That library README describes it as:

Is there a way to guarantee that a number variable can never be a non-finite value?
You can also look at the fp-ts ecosystem for inspiration. newtype-ts and io-ts's Branded type with io-ts-type's UUID as a good example

Branding & Flavoring
Alternatively we can use other more sophisticated techniques to achieve nominal typing or libraries such as: newtype-ts or io-ts.
