Today I Learned

Today I learned about the with method on the Array.prototype object. This method is used to create a shallow copy of an array but with one element replaced at a given index.

const arr = [1, 2, 3]
const newArr = arr.with(0, 5)

console.log(arr) // [1, 2, 3]
console.log(newArr) // [5, 2, 3]

This is useful when you want to replace elements in an array without mutating the original array.

So it’s even easier now to add a documentation website to your project! While looking over the Zod github repo, I saw that they were using docsify to house their documentation. It’s pretty slick and I intend to use it for my own projects… well at least the work ones 😆.

If you’re not using a meta framework like Next.js or Remix, I’d high suggest you check out react-error-boundary.

Seriously, Taran, use this at work.

TIL about how one can use satisfies in typescript, without satisfy at all!

// taken right from Kent's blog
type OperationFn = (left: number, right: number) => number

// this is a restriction on the operations object
// but with satisfies, I leave myself room to add more operations and don't need to manage another type
const operations = {
  '+': (left, right) => left + right,
  '-': (left, right) => left - right,
  '*': (left, right) => left * right,
  '/': (left, right) => left / right,
} satisfies Record<string, OperationFn>

Sick of seeing truncated Objects in Node? I got you bro (well Matt Pocock has got you).

let deepNesting = {
  level1: {
    level2: {
      level3: {
        level4: {
          level5: {
            name: 'Moderately Nested Object',
            value: 42,
            attributes: {
              created: '2023-10-01',
              modified: '2023-10-15',
              tags: ['demo', 'test', 'nested'],
              metadata: {
                author: 'Jane Doe',
                version: '1.0',
                license: 'MIT',
              },
            },
            items: [
              {
                id: 1,
                description: 'First item',
                status: 'active',
              },
              {
                id: 2,
                description: 'Second item',
                status: 'inactive',
              },
            ],
          },
        },
      },
    },
  },
}

// logs: { level1: { level2: { level3: [Object] } } }
console.log(deepNesting)

// You get the whole object!
console.dir(deepNesting, {depth: Infinity})

TIL that Storybook has a way to specify the behavior of args — ArgeTypes. This is a great way to constrain the values that your component can accept and provides information about args that aren’t explicitly set in the story.

// Replace your-renderer with the renderer you are using (e.g., react, vue3, angular, etc.)
import type {Preview} from '@storybook/your-renderer'

const preview: Preview = {
  argTypes: {
    // 👇 All stories expect a label arg
    label: {
      control: 'text',
      description: 'Overwritten description',
    },
  },
}

export default preview
