Dan Shapir introduces heap dumps to identify and fix Node.js memory and CPU issues. Memory leaks in JavaScript occur when objects are still reachable, impacting memory usage. Continuous memory rise from leaks can deplete memory and lead to CPU usage escalation. Detecting and resolving memory leaks promptly is crucial to prevent system unresponsiveness in production environments. Heap dumps and memory dumps help analyze memory issues, with Chrome DevTools aiding in finding memory leaks. Pinpointing memory leaks involves comparing heap snapshots and analyzing leaked objects. Alternative methods for generating heap snapshots include new experimental node flags, automatic triggers, and built-in APIs, offering benefits but posing risks such as potential crashes and security vulnerabilities.
