Subject: Functions, methods, closures, and function as arguments!
Notes
This week’s episode covers the basics of all sorts of functions: normal functions, methods, and closures.
Closures
An explanation (in Ruby) by Martin Fowler
Rust book
Rust by Example
“What is a closure?” (Progammers Stack Exchange) – the first answer is the best, but the second answer may be a helpful stepping stone for people just getting their heads around this and coming from OOP languages like C++ or Java (even though I disagree with the explanation in some ways).
“What is a closure?” (Stack Overflow) – careful, thorough answer using JavaScript as an example.
