interface HashMap<K,V>

A type-invariant immutable Map of key type K, and value type V. In the Map, each key has exactly one value, and the Map cannot contain duplicate keys. See the Map documentation and the HashMap API documentation

Companion namespace: HashMap

Implemented by: HashMapEmpty<K,V>, HashMap.NonEmpty<K,V>

Type parameters

Name	Description
K	the key type
V	the value type

note

• The HashMap uses the context's hasher instance to hash keys for performance.
  - The HashMap uses the context's eq function to determine equivalence between keys.

example

const m1 = HashMap.empty<number, string>()
const m2 = HashMap.of([1, 'a'], [2, 'b'])
