Promise Caching with Error Handling, Time Based Caching. | Javascript Top Rated Interview Question.

Описание: Promise caching is a technique used to improve performance by storing the results of promises, so that repeated calls to the same function do not require re-execution of the promise. This can be particularly useful in scenarios where fetching data from a remote server is involved.

How Promise Caching Works:

1. Check Cache: When a function that returns a promise is called, it first checks if the result is already in the cache.
2. Return Cached Result: If the result is found in the cache, it returns the cached result.
3. Execute Promise: If the result is not found, it executes the promise, stores the result in the cache, and then returns the result.
