/**
|
|
* 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
