TS Reset - Official Docs | Total TypeScript

without ts-reset

🚨 .json (in fetch) and JSON.parse both return any
🤦 .filter(Boolean) doesn't behave how you expect
😡 array.includes often breaks on readonly arrays

with ts-reset

👍 .json (in fetch) and JSON.parse return unknown
✅ .filter(Boolean) behaves EXACTLY how you expect
🥹 array.includes is widened to be more ergonomic
🚀 And several more improvements!

import '@total-typescript/ts-reset'
// .filter just got smarter!

const result = JSON.parse('{}') // unknown
fetch('/')

  .then((json) => {
    console.log(json) // unknown
