# Chapter 14 — Async Basics (Event Loop Thinking)
This chapter is diagram-first.
## 14.1 The Main Idea
Async is helpful when your program waits a lot (network requests, IO).
While waiting, it can do other work.
### Diagram: Waiting vs Doing
```text
Sync:
task A starts -> waits -> done -> task B starts -> waits -> done
Async:
task A starts -> waits
task B starts -> waits
whichever finishes first continues
```
## 14.2 Minimal async example
```python
import asyncio
async def work(name, seconds):
await asyncio.sleep(seconds)
return f"{name} done"
async def main():
a = asyncio.create_task(work("A", 1))
b = asyncio.create_task(work("B", 2))
print(await a)
print(await b)
asyncio.run(main())
```
