Then, import the function and use it in your code. Here's an example of using isWeakMap with type annotations:

index.ts
import { isWeakMap } from 'lodash';

const weakMap = new WeakMap();
const nonWeakMap = new Map();

console.log(isWeakMap(weakMap)); // true
console.log(isWeakMap(nonWeakMap)); // false

In this example, we're checking if a WeakMap and a regular Map are weak maps using isWeakMap. The function simply returns true if the input is a WeakMap and false otherwise.
