How does memory management affect JavaScript performance?

Memory management plays a crucial role in JavaScript performance. Efficient memory allocation and garbage collection can significantly reduce latency and improve the speed of applications.

What are some common memory management issues in JavaScript?

Common issues include memory leaks, excessive memory consumption, and inefficient garbage collection, which can lead to slow performance.

How can I optimize memory usage in my JavaScript code?

You can optimize memory usage by avoiding global variables, using closures wisely, and ensuring that you properly nullify references to objects that are no longer needed.

Are there tools to help monitor memory usage in JavaScript?

Yes, tools like Chrome DevTools, Node.js built-in profiler, and third-party libraries like Heap.js can help monitor and analyze memory usage.

What impact does garbage collection have on performance?

Garbage collection can introduce pauses in execution, which may affect performance. Optimizing memory allocation can help minimize these pauses.
