Logpoints are useful when you want output without editing source.\n\nIn the Sources panel:\n\n- **Pause on exceptions** for silent failures\n- **XHR\u002Ffetch breakpoints** when a response shape is wrong\n- **DOM breakpoints** when a node is removed or its attributes change unexpectedly\n\n## Filter the Network tab\n\nName your API calls clearly, then filter by Fetch\u002FXHR and status. Check the request payload and response body before blaming the renderer—many “UI bugs” are bad data arriving on time.\n\n## Inspect computed styles last\n\nWhen layout looks wrong, start with the box model and computed styles on the element, then walk up the tree. Flex\u002FGrid overlays show which container is actually controlling the layout.\n\n## Wrap-up\n\nTreat DevTools as part of your editor workflow. A few targeted breakpoints and network checks usually beat a long session of guess-and-refresh.",1784110285918]
