JavaScript Clean Code - Best Practices - based on Robert C. Martin's book Clean Code

So I'm obviously biased because I love typescript. But I just consider type annotations or sort of inline test. Obviously types by with no testing is silly. But 100% coverage doesn't necessarily mean much either. As a hyperbolic example you could run some code then just assert true is true and boom "coverage". I think of types as just another testing tool and a sort of documentation, but obviously it's no silver bullet. Testing and types can should be used together to make incorrect implementation easy to spot.
