Memoization Function — build a wrapper that returns cached result for same inputs without recomputing.

Given a products array, return frequency count sorted by frequency; equal frequency sorted in descending alphabetical order. Shoot the plane problem. How do you measure web performance and what metrics are used? Explain core web performance metrics — LCP, CLS, INP.

What types of frontend tests exist beyond unit testing and what are their differences and challenges? What storage options are available in the browser?
