What is Page Lifecycle in web development?

• A. The process of loading a CSS file.
• B. A series of steps for running a webpage within a web app.
• C. The life of a database page.
• D. The creation of a new user.

Answer: (B)

Page lifecycle is about the sequence of events a web page or component goes through while it’s active in a web application. It covers from the moment the page starts loading, through initialization, data binding, rendering to the document object model (DOM), becoming interactive, and finally when it’s navigated away or torn down. This understanding helps you manage when to fetch data, attach and detach event listeners, and perform cleanup so resources aren’t wasted and the page behaves reliably. Think of it as the lifecycle of the page’s existence within the app: it begins with loading, moves through setup and rendering, allows user interaction, and ends with removal or navigation. The option describing this as a series of steps for running a webpage within a web app matches that idea. The other ideas aren’t about the full sequence of a page’s existence. Loading a CSS file is one part of rendering but doesn’t describe the entire lifecycle. The life of a database page or creating a new user are unrelated concepts in this context.
