Node.jsのバージョンごとの設定

target は 変換後のコードのECMAScriptバージョンを指定する たとえば、Node.js 14はES2020をサポートしている。そのため、Node.js 14向けのコード(サーバなど)ならtarget: "ES2020"を指定することで、余計なTranspileが省かれててコードサイズや実行時間が最適化される。

import React from 'react';
import ReactDOM from 'react-dom';

let callCount = -1
let states = []

function useState(initValue) {
  const id = ++callCount
  
  if (states[id]) return states[id]

1. Learn in public

If there's a golden rule, it's this one, so I put it first. All the other rules are more or less elaborations of this rule #1.

You already know that you will never be done learning. But most people "learn in private", and lurk. They consume content without creating any themselves. Again, that's fine, but we're here to talk about being in the top quintile. What you do here is to have a habit of creating learning exhaust. Write blogs and tutorials and cheatsheets. Speak at meetups and conferences. Ask and answer things on Stackoverflow or Reddit. (Avoid the walled gardens like Slack and Discourse, they're not public). Make Youtube videos

// Since ES6 Map()'s' retain their order of insertion, it can sometimes be useful to get the last item or value inserted:

export const getLastItemInMap = map => Array.from(map)[map.size-1]
export const getLastKeyInMap = map => Array.from(map)[map.size-1][0]
export const getLastValueInMap = map => Array.from(map)[map.size-1][1]

// Obviously getLastKey and getLastValue can reuse getLastItem, but for maximum portability I opted for verbosity.
