alterF<F>(f): (<V>(updater) => (<K>(key) => ((m) => Get1<F, Map<K, V>>)))
Alternates entry with the key over the functor F. This lets you insert, modify and remove an entry contained by F.
Type Parameters
- F
Parameters
- f: Functor<F>
  The Functor instance for F.
Returns (<V>(updater) => (<K>(key) => ((m) => Get1<F, Map<K, V>>)))
A new Map with the replaced entry.
- - <V>(updater): (<K>(key) => ((m) => Get1<F, Map<K, V>>))
  - Type Parameters
    - V
    Parameters
    - updater: ((oldEntry) => Get1<F, Option<V>>)
      (oldEntry): Get1<F, Option<V>>
      Parameters
      oldEntry: Option<V>
      Returns Get1<F, Option<V>>
    Returns (<K>(key) => ((m) => Get1<F, Map<K, V>>))
    - - <K>(key): ((m) => Get1<F, Map<K, V>>)
      - Type Parameters
        K
        Parameters
        key: K
        Returns ((m) => Get1<F, Map<K, V>>)
