Key ideas in Building Web Apps with Angular
- An Angular component combines an HTML template, CSS styles, and a TypeScript logic class into a single unit
- The component's selector defines a custom HTML tag that renders that entire bundle wherever you place it
- Double curly braces {{ }} tell Angular to read a property from the TypeScript class and print its value in the HTML
- When the class property value changes, Angular automatically updates the text displayed inside the curly braces
- Parentheses around a DOM event name (such as (click)) bind user actions to methods in the TypeScript class
- Parentheses represent data moving outward from the template into your TypeScript logic
- Square brackets around an HTML attribute tell Angular to evaluate the right-hand value as an expression from your TypeScript class
- Leaving off square brackets (e.g. disabled="isSubmitting") treats the value as a plain literal string instead of reading the component variable
- The Angular CLI uses 'ng generate component <name>' (or 'ng g c <name>') to scaffold boilerplate files instantly
- The command creates the TypeScript, HTML, CSS/SCSS, and test files together and registers the component automatically
- A signal holds a value and notifies Angular whenever that value is updated
- Calling .set() on a signal tells Angular exactly which parts of the template need an update
- Angular handles DOM updates automatically without manual DOM manipulation
- A computed signal derives its value by reading other signals
- Angular tracks those dependencies and recomputes the derived value whenever an input signal changes
- You do not need to manually trigger calculations or write event listeners to keep derived data fresh

Here's what playing it feels like
A real question from this course. Take your best guess.
Imagine you created a user profile component with the selector 'app-user-profile'. How do you display it on your screen?
