API:

// commonych/ArrayFn
export class ArrayFn
{
    public static chunkArray<T>(array: T[], chunkSize: number): T[][];

    public static fillKeys<K extends (number|string|symbol), T>(
        keys: K[], 
        val: T
    ): {[P in K]: T};

    public static groupBy<
        K extends string|number|symbol,
        T extends {[Key in K]: string|symbol|number}
    >(k: K, ts: T[]): {[Key in T[K]]: T[]};

    public static unique<T>(
        arr: T[], 
        includesCheck: ((acc:T[], b:T) => boolean)|null = null
    ): T[];
}

// commonych/BigIntFn
