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

ts-reset smooths over these hard edges, just like a CSS reset does in the browser.

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!
