Javascript Programming Tutorials, Guides & Best Practices

• Memory Leaks: Closures can cause memory leaks if they inadvertently keep references to variables or objects that are no longer needed, preventing them from being garbage collected.
• Unintended Retention of State: If not managed carefully, closures can lead to unexpected retention of state, leading to bugs that are difficult to track down.

To avoid these issues, always ensure that closures are used intentionally and that any unnecessary references are removed.
