How can I analyze memory usage in Chrome DevTools?

You can analyze memory usage in Chrome DevTools by using the Memory panel. It allows you to take heap snapshots, record allocation timelines, and analyze memory leaks.

What are heap snapshots and how do I take one?

Heap snapshots are a way to capture the memory allocation of your application at a specific point in time. To take one, go to the Memory panel, select 'Take snapshot', and it will capture the current state.

How can I identify memory leaks using these snapshots?

To identify memory leaks, compare multiple heap snapshots. Look for objects that are retained in memory between snapshots that should have been garbage collected.

Are there any tools or features in DevTools that help with memory analysis?

Yes, besides heap snapshots, you can use the Allocation Timeline to see memory allocation over time and the Garbage Collection feature to manually trigger garbage collection and observe its effects.
