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