The injector is a crucial component of the Angular framework. Explain how the injector works, including its role in dependency injection and the different types of injectors.
Decoded: Frontend Angular Interview Hacking – The Ultimate Guide to Landing Your Senior Role
Decoding Frontend: Angular Interview Hacking Preparing for an Angular interview can feel like trying to memorize the entire framework documentation. But "hacking" the interview isn’t about knowing every API; it’s about understanding the core architectural patterns and knowing how to communicate your expertise effectively.
Ignores new incoming observables while the current inner observable is still executing. This is perfect for preventing double-submits on login buttons. 3. The Modern Angular Paradigm: Signals decoded frontend angular interview hacking

Most technical assessments focus on these three interconnected areas: But "hacking" the interview isn’t about knowing every
@Self() : Tells Angular to look only in the local element injector of the current component.
Explain that mutating an object property will not trigger an update under OnPush because the object reference remains the same. You must enforce immutability (e.g., using the spread operator or libraries like Immer) to make OnPush work correctly. Signals vs. RxJS
