# Reusability
## MicroSim spec
- **Recommended sim type:** library / reuse
- **Microsimmability score:** 79/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Generality`
- `Coupling to context`
- `Reuse instances`
### What animates
A component is reused across projects; cumulative cost savings grow as generality rises and context [[Coupling|coupling]] falls.
### Learning objective
Relate reuse payoff to generality and contextual coupling.

## Concept summary
Reusability is the degree to which a component can be used again in new contexts, amortizing development cost.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to system quality attributes)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Reusability
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render library / reuse; respond live.
}
```
