Type Path returns all possible variants of the key for the function lodash.get
type ValueOf<T> = T[keyof T];
type ArrayPath<T> =
T extends Array<unknown>
? ArrayPath<Omit<T, keyof []>>
: T extends object
? ValueOf<{
[K in keyof T]: [K] | [K, ...ArrayPath<T[K]>];
}>
: never;

restore

https://effector.now.sh/en/api/effector/restore

Используется тогда, когда необходимо из ивента напрямую выставить значение в стор в обход .on.

Аналог без restore:

const $store = createStore('');
const event = createEvent();
$store.on(event, (_, payload) => payload);

Functional acrobatics using folds in JavaScript.
/*eslint-env es6 */
// Inspired by the paper "A tutorial on the universality and
// expressiveness of fold" by Graham Hutton (available at
// http://www.cs.nott.ac.uk/~gmh/fold.pdf), implementing some generic
// list handling functions in JavaScript in terms of `fold`.
// Personally I had an enlightnening moment when I realised the
// beautiful interplay of cons lists and foldr during the FP101x
// Haskell course. JavaScript's syntax doesn't make this very apparent
