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
