🧩 JavaScript Closures 🧩

#techlife #javascript #100daysofcode #codinglife

I've been exploring the power of JavaScript closures. Closures are a fundamental concept in JavaScript that allow functions to retain access to their lexical scope, even when executed outside of that scope. This can be incredibly useful for creating private variables and functions.

5 Playwright CLI Flags That Will Transform Your Testing Workflow

0:56 --last-failed: Zero in on just the tests that failed in your previous run

2:34 --only-changed: Test only the spec files you've modified in git

4:27 --repeat-each: Run tests multiple times to catch flaky behavior before it reaches production

5:15 --forbid-only: Prevent accidental test.only commits from breaking your CI pipeline

5:51 --ui --headed --workers 1: Debug visually with browser windows and sequential test execution
