A 'CSS reset' for TypeScript that improves the built-in typings for common JavaScript APIs like JSON.parse, fetch's .(), .filter(Boolean), and array.includes. It is imported once in a declaration file to apply safer, more ergonomic types across an entire project.

Use cases

• make JSON.parse return unknown instead of any
• make fetch response .() return unknown
• make .filter(Boolean) narrow array types correctly
• fix array.includes errors on readonly arrays
• make localStorage and sessionStorage return unknown
• improve TypeScript's built-in lib typings project-wide

When to choose

• you want safer default typings for JSON parsing and fetch in a TypeScript project
• you're tired of any leaking in from JSON.parse and res.()
• you want .filter(Boolean) to narrow types without casts
• you want a single-import, opt-in set of improved built-in typings

When to avoid

• you need strict control over every type declaration and don't want global ambient changes
• your project depends on the exact current behavior of the standard lib typings
• you're not using TypeScript
