implement memoizeOne()

Question

In problem 14. Implement a general memoization function, you are asked to implement a memo function without space concern.

But in reality, it could be a problem if cache bloats.

You might need to restrict the cache capacity, just like memoize-one , it only remembers the latest arguments and result.

Please implement your own memoizeOne(), it takes 2 arguments

1. target function
2. (optional) a equality check function to compare current and last arguments

Default equality check function should be a shallow comparison on array items with strict equal ===.

Code

/**
 * @param {Function} func
 * @param {(args: any[], newArgs: any[]) => boolean} [isEqual]
 * @returns {any}
 */

function memoizeOne(func, isEqual) {
  // your code here
}
