Set<Subscriber> | undefined

includes()

includes(searchElement: T, fromIndex?: number): boolean;

Defined in: src/reactivity/signals/reactive-array.ts:464

Returns

boolean

indexOf()

indexOf(searchElement: T, fromIndex?: number): number;

Defined in: src/reactivity/signals/reactive-array.ts:457

Returns

number

join()

join(separator?: string): string;

Defined in: src/reactivity/signals/reactive-array.ts:508

Parameters

Parameter	Type
`separator?`	`string`

Returns

string

keys()

keys(): IterableIterator<number>;

Defined in: src/reactivity/signals/reactive-array.ts:539

Returns

IterableIterator<number>

map()

map<U>(callback: (value: T, index: number, array: T[]) => U): ReactiveArray<U>;

Defined in: src/reactivity/signals/reactive-array.ts:310

map() ahora retorna un ReactiveArray derivado, no un array plano Este es el corazón de tu insight: mantener la reactividad en la cadena

MEMOIZACIÓN INTELIGENTE:

Cachea el array derivado por toString() del callback
Captura dependencias externas (signals que el callback lee)
Si las dependencias no cambiaron, retorna el MISMO array derivado
Esto permite granularidad: push/pop solo afectan nuevos elementos

`U`
