# HashMap<K, V>.from constructor

HashMap<K, V>.from(Map other)

Creates a HashMap that contains all key/value pairs of `other`.

The keys must all be instances of `K` and the values of `V`. The `other` map itself can have any type.

## Implementation

    factory HashMap.from(Map other) {
      Map<K, V> result = HashMap<K, V>();
      other.forEach((k, v) {
        result[k] = v;
      });
      return result;
    }
