A convenience function for safely accessing values in dynamic objects and arrays. It gets the value at a specified key or index, and throws an error if the resulting value is undefined.

• TypeScript assertions for type narrowing
• Works with both objects and arrays
• Supports negative indexing for arrays
• Allows for custom error messages
• Zero dependencies
• Provides got as alias for getOrThrow

pnpm add get-or-throw

import { got } from "get-or-throw";

const arr = [1, 2, 3];
got(arr, 1); // 2

const obj = { a: 1, b: 2, c: 3 };
got(obj, "b"); // 2
