JSTools Weekly — ✨2023#8: TS-Reset: A ‘CSS reset’ For TS, Improving JS Types

Hi JS developers👋
JSTools Weekly newsletter, issue 2023#8 (top new JS releases) just released.

new JS tools, issue 2023#8

ts-reset: A 'CSS reset' for TypeScript, improving types for common JavaScript API's

With ts-reset:

  • 👍 .json (in fetch) and JSON.parse both return unknown

  • .filter(Boolean) behaves EXACTLY how you expect

  • 🥹 array.includes is widened to be more ergonomic

  • 🚀 And several more changes!

// Import in a single file, then across your whole project...
import "@total-typescript/ts-reset";

// .filter just got smarter!
const filteredArray = [1, 2, undefined].filter(Boolean); // number[]

// Get rid of the any's in JSON.parse and fetch
const result = JSON.parse("{}"); // unknown

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