## usage

Initialize the memoization store. The store will keep the memoized objects

for as long as the originals are not garbage collected (it uses a WeakMap).

```

const memoizeMethods = createMemoizeMethods()

```

```

const memoizedUserRepository = memoizeMethods(slowUserDbRepository)

```

the first call will be as slow as if we'd called the original user repo

```

const user = await memoizedUserRepository.getUser(userId) // slow

```

the second call will return the promise from the previous call which prevents

the unnecessary repeated async call (e.g. towards a slow db)

```

const userFast = await memoizedUserRepository.getUser(userId) // fast

```
