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...
