432: The Semantics and Meaning of Nil

July 9th, 2024  |  38 mins 13 secs

The term ‘nil’ refers to the absence of value, but we often imbue it with much more meaning than just that. Today, hosts Joël and Stephanie discuss the various ways we tend to project extra semantics onto nil and the implications of this before unpacking potential alternatives and trade-offs. 

Joël and Stephanie highlight some of the key ways programmers project additional meaning onto nil (and why), like when it’s used to create a guest session, and how this can lead to bugs, confusion, and poor user experiences. They discuss solutions to this problem, like introducing objects for improved readability, before taking a closer look at the implications of excessive guard clauses in code.
