Overview

Check out the regular Intermediate CS course’s Pro Features section. We will use it for for loops and matching.

Useful Topics

• Structures (not nearly as useful as other material)!

• Match

• For “Loops” (a misnomer in Racket): for/list and for/fold.

• Symbols

• Association Lists

• Quoting and Quasiquoting - making templates.

• Multiple values. (Optional.) One legitimate use: updating two “accumulators” in for/fold. Usually not appropriate; consider returning a structure instead.
