What are memory leaks in JavaScript?

Can you explain what memory leaks are in JavaScript?

Sure! Memory leaks in JavaScript occur when the program retains references to objects that are no longer needed, preventing the garbage collector from reclaiming that memory.

What are some common causes of memory leaks?

Common causes include global variables, forgotten timers or callbacks, and closures that hold onto variables.

How can I detect memory leaks in my JavaScript code?

You can use browser developer tools to monitor memory usage and look for increasing memory consumption over time.

What are some best practices to avoid memory leaks?

Best practices include using local variables, clearing timers and event listeners, and avoiding global variables.
