Embark on a crash course in semantic theory to unpack the challenging task of naming in software engineering. Explore how names function as a linguistic front-end, concealing a complex backend of unseen associations. Begin with a single variable name and progressively zoom out to the broader perspective of domain-driven design, examining the significant impact of naming at each stage. Gain insights to enhance your code, regardless of your experience level, in this 29-minute conference talk presented at RailsConf 2024 by Karynn Ikeda.
