Memory Management & Garbage Collection

Arrow functions typically have a lower memory impact: 1) They don't create their own 'this', 'arguments', 'super', or 'new.target' bindings, 2) This reduced overhead makes them slightly more memory-efficient for many use cases, 3) The difference is especially relevant when creating many function instances, like in event handlers or callbacks, 4) In modern JavaScript engines, the optimization can be significant for applications creating thousands of function objects, 5) Regular functions require additional memory to maintain their own execution context, 6) However, the actual impact depends on the specific JavaScript engine implementation, 7) For most applications, the difference is minimal and other factors are more important for memory optimization, 8) This represents a micro-optimization that becomes meaningful at scale or in memory-constrained environments.
