new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

3 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

Logger usage example with chromium

Example code: const { chromium } = require('playwright'); (async () => { const browser = await chromium.launch({ logger: { isEnabled: (name, severity) => name === 'api', log: (name, severity, message, args) => console.log(`${name} ${message}`) } }); })();

Logger configuration in browser launch

Logger can be configured when launching a browser by passing a logger object to the launch options. The logger object should have isEnabled and log methods. The isEnabled method filters which logs to process, and the log method handles the actual logging.

Logger class deprecated, use tracing instead

The Logger class is deprecated as of v1.8. The logs pumped through this class are incomplete. Users should use tracing instead.
