Cheat sheet: JavaScript Array methods

Deriving a new Array from an existing Array:

['■','●','▲'].slice(1, 3)           ['●','▲']
['■','●','■'].filter(x => x==='■')  ['■','■']
    ['▲','●'].map(x => x+x)         ['▲▲','●●']
    ['▲','●'].flatMap(x => [x,x])   ['▲','▲','●','●']

Краткая характеристика:

  1. У него много сторов и сторы могут зависеть друг от друга, а не один большой стор и селекторы. То есть он ближе к Эфектору, чем в Редаксу/MobX. Всё ради tree shaking.
  2. Он ближе к стору прямых измений. В публичном API нет экшенов. Но всё-таки value = 1 на манер MobX запрещены — значения можно менять только через спец. методы. И в синхронизации состояния с сервером экшены есть (просто скрыты из публичного API).

Плюсы:

  1. Может работать без Логакса, чисто как стейт-менеджер.
  2. API специально создан, чтобы хранить в сторах бизнес-логику, чем разгружать компоненты и упрощать переносимость приложения между фреймворками.
  3. От 157 байт (!) в вашем JS-бандле.
  4. Расчитан на агрессивный tree shaking, чтобы в JS-бандле был только код того состояния, которые используются в текущих страницах.
  5. Очень ленивый — сторы на которых никто не подписан выгружаются из памяти, а их бизнес-логика останавливается.

Pure ESM package

The package linked to from here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.

Function syntaxes supported by TypeScript

The blog post has been written: https://kentcdodds.com/blog/typescript-function-syntaxes

TypeScript Function Syntaxes

I'm trying to create examples of all the different ways to write functions and function type definitions in TypeScript.

One requirement is these examples must work with strict mode (noImplicitAny, etc) enabled.

If I'm missing anything, please add comments below with examples. I'll eventually put this into a blog post.

Storybook experimental Webpack 5 support

Storybook 6.2 includes experimental Webpack 5 support. Webpack 5 brings a variety of performance improvements, as well as exciting new features like module federation. Here's a quick guide to get you going.

Intro

Storybook uses webpack to bundle its UI ("manager") and also user code in an iframe ("preview"). In Storybook 6.2, the manager is bundled in Webpack 4, and the preview can either be bundled in Webpack 4 (default) or Webpack 5 (opt-in). In Storybook 6.3, the manager is also bundled in Webpack 5 when the preview is bundled with Webpack 5.

Zig in 30 minutes
View test.md

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)
