Episode notes

INSIGHT

Power in Omission?

Omitting features cannot make a language more powerful.
Functional programming’s power lies in enabling new ways of modularization.

INSIGHT

Glue and Modularity

The way problems are decomposed depends on how solutions are combined.
New kinds of "glue" increase modularization possibilities.

ANECDOTE

Higher-Order Functions: foldR

Eric Normand explains how higher-order functions like foldR enable code reuse.
foldR generalizes list operations by replacing cons with a function and nil with a value.
