## Cache Property Access in Loops
|
||
|
||
Cache object property lookups in hot paths.
|
||
|
||
**Incorrect (3 lookups × N iterations):**
|
||
|
||
```typescript
|
||
for (let i = 0; i < arr.length; i++) {
|
||
process(obj.config.settings.value)
|
||
}
|
||
```
|
||
|
||
**Correct (1 lookup total):**
|
||
|
||
```typescript
|
||
const value = obj.config.settings.value
|
||
const len = arr.length
|
||
for (let i = 0; i < len; i++) {
|
||
process(value)
|
||
}
|
||
```
