Learn Go by writing tests – Hello, world (2018)
OT but it this decade not more about types than tests?<p>Edit: Since this seems to be an unpopular opinion why stop here, haha: The more one stresses tests the more he/she signals that he must have missed years of advancements in software engineering. If you do this with peers, ok, but publicly? Even Ruby added types, not the kind of types we hoped for but still, it's a strong signal. If your lang has a mature type system you don't need half of your tests anymore and might not be into such write-ups. Praising and writing gazillions of tests don't make you look smarter, very much the opposite.
