Function getOrCreateCached

getOrCreateCached<T>(
    cache: Map<string, T>,
    key: string,
    limit: number,
    create: () => T,
): T
Reads key from cache, creating and storing it on a miss.

Bounded as a true LRU: at limit, only the single least-recently-used entry is evicted, and reading an existing key promotes it by re-inserting it. Exported because the same eviction logic is useful for a consumer's own caches.
Type Parameters
- T
Parameters
- cache: Map<string, T>
- key: string
- limit: number
- create: () => T

Example

const cache = new Map<string, Expensive>();
const value = getOrCreateCached(cache, 'key', 100, () => new Expensive());
```
