brings clojure/midjes meta-constants (https://github.com/marick/Midje/wiki/Metaconstants) to javascript
a meta-constant replaces this testing pattern:
expect(identity(42)).toBe(42);
with
expect(identity(_$_`a-number`)).toBe(_$_`a-number`);
Although this is longer, it makes clear that the value is only threaded through the function under test and any (number) will do.
meta-constants only provide identity. If your function under test requires more than
that from a value, you need a real value
The template functionality isn't used used?!
Answer:
- syntactical difference
- template functionality may become useful later...
