What are some effective tools for detecting memory leaks in JavaScript?

There are several tools you can use to detect memory leaks in JavaScript, such as Chrome DevTools, Node.js built-in tools, and third-party libraries like Memwatch and LeakCanary.

How do I use Chrome DevTools to find memory leaks?

To use Chrome DevTools, open the DevTools, go to the 'Memory' tab, and take a heap snapshot. You can then compare snapshots to identify objects that are not being garbage collected.

What are some common signs of memory leaks in my application?

Common signs include increased memory usage over time, slow performance, and crashes. If your app's memory usage keeps growing without being released, that's a strong indicator.

Can you recommend any best practices to prevent memory leaks?

Yes! Some best practices include properly managing event listeners, avoiding global variables, and using weak references when necessary.
