/**
* Checks if the given value is a `WeakMap`.
*
* This function tests whether the provided value is an instance of `WeakMap`.
* It returns `true` if the value is a `WeakMap`, and `false` otherwise.
*
* This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to `WeakMap`.
*
* @param {unknown} value - The value to test if it is a `WeakMap`.
* @returns {value is WeakMap<WeakKey, any>} true if the value is a `WeakMap`, false otherwise.
*
* @example
* const value1 = new WeakMap();
* const value2 = new Map();
* const value3 = new Set();
*
* console.log(isWeakMap(value1)); // true
* console.log(isWeakMap(value2)); // false
* console.log(isWeakMap(value3)); // false
