  • Returns number

    the number of elements in the Map.

Methods

[iterator]

  • [iterator](): IterableIterator<[K, V]>

  • Returns IterableIterator<[K, V]>

entries

  • entries(): IterableIterator<[K, V]>

  • Returns IterableIterator<[K, V]>

get

  • get(key): undefined | V

  • Returns a specified element from the Map object. If the value that is associated to the provided key is an object, then you will get a reference to that object and any change made to that object will effectively modify it inside the Map.

    Parameters

    Returns undefined | V

    Returns the element associated with the specified key. If no element is associated with the specified key, undefined is returned.

getOrThrow

  • getOrThrow(key): V

  • Parameters

    Returns V

has

  • has(key): boolean

  • Parameters

    • key: K

    Returns boolean

    boolean indicating whether an element with the specified key exists or not.

keys

  • keys(): IterableIterator<K>

  • Returns IterableIterator<K>

toMutableMap

  • toMutableMap(): Map<K, V>

  • Returns Map<K, V>

values

  • values(): IterableIterator<V>

  • Returns IterableIterator<V>
