are synchronous and represent a value that changes over time. They are excellent for managing local UI state because they track dependencies automatically, eliminating the need for zone.js in future applications.
Move beyond "I use Jasmine/Karma." Discuss Component Harnesses in Angular Material or switching to Cypress/Playwright for E2E testing. Mentioning Jest for faster unit test execution shows you care about the developer experience (DX). The "Hacker’s" Final Tip: The Why, Not the How Explain the different types of data binding in
