The video discusses memory leaks in Node.js applications, explaining how to identify, understand, and debug them. It covers concepts like expected lifetimes of objects, tools for debugging memory leaks, and provides insights into native memory leaks as well.

Understanding memory leaks and their impact on code is crucial. Despite the challenge of completely avoiding memory leaks, taking proactive steps like writing clean code and being cautious with external modules can help mitigate the risk.

Exploring tools for debugging memory leaks, focusing on native, Java, and JavaScript leaks. Discusses monitoring memory consumption, resident set size, heap total, heap used, and external memory to identify and address memory leaks effectively.

The chapter introduces advanced memory profiling tools like Allocation Timeline and Sampling Profiler, offering detailed insights into memory allocation patterns. It emphasizes the importance of using these tools proactively to detect and address memory leaks in production environments.
