COOPERATIVE MULTITASKING
WITH GENERATORS
(please sit up front)
Hi, I'm Chris
We spend a lot of time waiting...
...But we can write asynchronous code.
Arrays
Array-likes
Iterators
Talk about generators!
Reading files
Sorting
Pure functions are like
data tables...
| a + b | a - b | |
|---|---|---|
| a = 5, b = 4 | 9 | 1 |
| a = 10, b = 10 | 20 | 0 |
| 0 | 1 | 9 | 20 | |
|---|---|---|---|---|
| a = 5, b = 4 | ... | a - b | a + b | ... |
| a = 10, b = 10 | a - b | ... | ... | a + b |
Task manager
Generators can be used as interruptible functions
Otherwise known as coroutines
Asynchronous architecture in about 65 lines of code

Cooperative Multitasking with Generators

Cooperative Multitasking with Generators
Have you ever used the yield keyword? It's the hidden-wardrobe-entrance into a magical world of generators. This magical world is inhabited by beings called iterators and coroutines. Roll some epic battle-music...
