Properties

"[toStringTag]": string
limit: number
size: number

the number of elements in the Map.

"[species]": MapConstructor

Accessors

  • get empty(): boolean

    If this collection is empty.

    Returns boolean

Methods

  • Returns an iterable of entries in the map.

    Returns IterableIterator<[K, C]>

  • Returns void

  • Parameters

    • key: K

    Returns boolean

    true if an element in the Map existed and has been removed, or false if the element does not exist.

  • Returns an iterable of key, value pairs for every entry in the map.

    Returns IterableIterator<[K, C]>

  • Executes a provided function once per each key/value pair in the Map, in insertion order.

    Parameters

    • callbackfn: (value: C, key: K, map: Map<K, C>) => void
    • OptionalthisArg: any

    Returns void

  • 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

    • key: K

    Returns undefined | C

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

  • Parameters

    • key: K

    Returns boolean

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

  • Returns an iterable of keys in the map

    Returns IterableIterator<K>

  • See: Array#map

    Type Parameters

    • T

    Parameters

    • predicate: (value: C, index: number, obj: C[]) => T
    • OptionalthisArg: unknown

    Returns T[]

  • Parameters

    • predicate: (previousValue: C, currentValue: C, currentIndex: number, array: C[]) => C

    Returns C

  • Parameters

    • predicate: (previousValue: C, currentValue: C, currentIndex: number, array: C[]) => C
    • initialValue: C

    Returns C

  • Type Parameters

    • T

    Parameters

    • predicate: (previousValue: T, currentValue: C, currentIndex: number, array: C[]) => T
    • initialValue: T

    Returns T

  • Parameters

    • predicate: (previousValue: C, currentValue: C, currentIndex: number, array: C[]) => C

    Returns C

  • Parameters

    • predicate: (previousValue: C, currentValue: C, currentIndex: number, array: C[]) => C
    • initialValue: C

    Returns C

  • Type Parameters

    • T

    Parameters

    • predicate: (previousValue: T, currentValue: C, currentIndex: number, array: C[]) => T
    • initialValue: T

    Returns T

  • Adds a new element with a specified key and value to the Map. If an element with the same key already exists, the element will be updated.

    Parameters

    • key: K
    • value: C

    Returns this

  • Returns an iterable of values in the map

    Returns IterableIterator<C>
