Array Iteration

https://gist.github.com/ljharb/58faf1cfcb4e6808f74aae4ef7944cff

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu

// Counter Component
import React, { useReducer, createContext } from 'react'
import reducer, { initialState, actions } from './reducer'

const CounterContext = createContext()

function Counter() {
  const [state, dispatch] = useReducer(reducer, initialState)
  const { increment, decrement, reset } = actions(dispatch)

// One of my new favorite React Hook patternms is to create handler
// functions for a custom hook using `React.useMemo` instead of
// `React.useCallback`, like so:

function useBool(initialState = false) {
  const [state, setState] = React.useState(initialState)
  
  // Instead of individual React.useCallbacks gathered into an object
  // Let's memoize the whole object. Then, we can destructure the
  // methods we need in our consuming component.

How to use async/await without try/catch block

We can use something like this:

async function resolveToNumber () {
  const promise = Promise.resolve(1)
  const [error, result] = await to(promise)
  console.log(error, result) // [null, 1] -> Here we have the result, and error will be null
}

const run = async () => {
  const payload = {
    field: 'value'
  }
  
  const options = {
    method: 'POST',
    headers: {
