Determining when to abstract is one of the constant challenges of engineering.

Abstracting too soon often creates as many problems as abstracting concepts too late.

Sandy Metz has been talking and writing about this since 2014, e.g., The Wrong Abstraction.

Kent C. Dodds adopted Sandy’s philsophy in his AHA Programming. AHA being an acronym for Avoid Hasty Abstractions.
