Memory Management & Garbage Collection

Which memory management practice does this code demonstrate?

let globalCache = {};

function loadData(id) {
  if (!globalCache[id]) {
    globalCache[id] = fetchDataFromServer(id);
  }
  return globalCache[id];
}

// In another part of the code
function clearCache() {
  globalCache = {};
}

Memory pooling
Explicit cache control
This code demonstrates explicit cache control: 1) It maintains a global cache object to store and reuse fetched data, 2) It provides a clearCache function to explicitly release all cached data at once, 3) This gives developers direct control over memory usage and cache lifecycle, 4) The approach prevents duplicate fetches while allowing memory to be reclaimed when needed, 5) This pattern is useful for managing memory in long-running applications, especially with large data sets, 6) Explicit cache control is particularly important when automatic garbage collection isn't sufficient for memory management needs, 7) It allows coordination of memory usage with application states or events, 8) However, this global approach should be used carefully as it could lead to namespace collisions or memory leaks if clearCache isn't called appropriately.
