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);

function getStack() {
    // Save original Error.prepareStackTrace
    const origPrepareStackTrace = Error.prepareStackTrace;

    // Override with function that just returns `stack`
    Error.prepareStackTrace = (_, stack) => stack;

    // Create a new `Error`, which automatically gets `stack`
    // Evaluate `err.stack`, which calls our new `Error.prepareStackTrace`
    const { stack } = new Error();

Usage of createStoreMap

Create $todos store (with an array) using createStore. Then create a $todoList store using createStoreMap.

There will be a map inside of $todoList store. Define map keys with getKey function and values with createValue function. A value object should contain a store inside which will represent an item of your $todos array. Provide this store with a getStore function.

As a result, $todoList will contain a map of value-objects (by keys). Each object will contain an item-store (with an item of a mapped array)

You can filter, map, concat or do anything you want with items of an array inside $todos.

So there were a few threads going around recently about a challenge to write the longest sequence of keywords in Javascript:

• https://twitter.com/bterlson/status/1093624668903268352
• https://news.ycombinator.com/item?id=19102367

There are, however, a few problems:

• These solutions use non-keyword tokens (null, true, false are actually Literals, not Keywords)
• One of the solutions isn't quite valid (new super)

const createConcurrentRequest = () => {
  let lastReq;
  return async (request, ...params) => {
    let myReq = (lastReq = request(...params));
    let response = null;
    let error = null;

    do {
      try {
        error = null;

Введение

Конктруктор - является значением. Им можно оперировать в программе как любым дригим значением, Например как строкой или числом

Тип - работает так же как и в других языках
