Reviewer Prompt

Identify and eliminate unnecessary duplicate operations, redundant function calls, and repeated computations that can impact performance. Common patterns include: avoiding redundant parameter retrieval when values are already available, preventing duplicate map lookups by caching results, checking for changes before performing expensive operations, and caching expensive computations for reuse.

Examples of optimization opportunities:

  • Pass available parameters instead of recalculating: UpdateWindowAccentColor(active) rather than calling IsActive() again
  • Cache map lookup results: if (const auto* orig = base::FindOrNull(options.environment, key)) instead of separate find() and second lookup
  • Guard expensive operations with change detection: if (title == GetTitle()) return; before triggering update events
  • Cache expensive computations in static storage: base::NoDestructor<std::string> for values computed repeatedly during module loading
  • Reuse V8 string objects: Create v8::Local<v8::String> keys once and reuse them instead of recreating identical strings multiple times

Consider debouncing rapidly-triggered operations like window state saves during resize events to prevent performance degradation from excessive I/O operations.
