FunkyArray

An array that supports both iteration and key value indexing.

Usage

Create a new instance of FunkyArray

JavaScript

const funkyArray = new FunkyArray();

TypeScript

const funkyArray = new FunkyArray<key_type, value_type>();

From here you can set or remove items by an a key of key_type

For example:

const users = new FunkyArray<string, User>();
const user = new User(1, "Username", crypto.randomUUID());
users.set(user.uuid, user);

General concepts

FunkyArray uses an internal "itteration array" which is really just a regular js array with all the keys. Whenever you see a regenerate:boolean in a method, this is so you can not regenerate the "itteration array" if you are bulk inserting things. In general you want to be very careful when turning this off and it can break itteration.

Methods

  • set(key:T, item:TT, regenerate:boolean = true) : TT

    Sets the corrosponding key in the array to the given value. If an existing array key is provided the existing value is overwritten.

  • remove(key:T, regenerate:boolean = true) : boolean

    Removes an item from the array by key.
    Returns a boolean of remove success.

  • removeFirst(regenerate:boolean = true)

    Removes the first item in the array
    Returns a boolean of remove success.

  • first() : TT

    Returns the first item in the array.

  • get(key:T) : TT | undefined

    Returns the item with the given key, if it does not exist it returns undefined.

  • has(key:T) : boolean

    Returns a boolean for if a value exists for the given key.

  • forEach(callback: (value:TT) => void) : Promise<boolean>

    Functionally equivilent to Array.forEach Returns a boolean promise that resolves once the forEach itteration is complete.

Getters

  • length : number

    Returns the number of key values in the FunkyArray.

  • keys : Array<T>

    Returns an array of the FunkyArray's keys.
