Usage

After installation the library can be imported as such:

The interface is similar to the standard Map, but extended to support multiple keys:

interface MultiKeyMap<KS extends unknown[], V> {
    *[Symbol.iterator](): IterableIterator<[KS, V]>
    constructor(entries?: readonly (readonly [...KS, V])[] | null)
    clear(): void
    delete(...keys: KS): boolean
    *entries(): IterableIterator<[KS, V]>
    forEach(callbackfn: (value: V, keys: KS, multiKeyMap: MultiKeyMap<KS, V>) => void, thisArg?: any): void
    get(...keys: KS): V | undefined
    has(...keys: KS): boolean
    *keys(): IterableIterator<KS>
    set(...keysValue: [...KS, V]): this
    get size(): number
    toString(): string
    *values(): IterableIterator<V>
}
