Angular Event Binding: Interactive Button Counter
This challenge focuses on a fundamental Angular concept: event binding. You will create an interactive component that responds to user actions by updating its internal state and displaying the result. This is a crucial skill for building dynamic and user-friendly web applications in Angular.
Problem Description
Your task is to create an Angular component that displays a counter and a button. When the button is clicked, the counter should increment by one.
Key Requirements:
- Create a new Angular component.
- The component should have a property to store the current count, initialized to 0.
- The component's template should display the current count.
- The component's template should include a button.
- When the button is clicked, an event handler method in the component should be triggered.
- This event handler method should increment the count property.
Expected Behavior:
- Initially, the component displays "Count: 0".
- Each time the button is clicked, the displayed count increments by one (e.g., "Count: 1", "Count: 2", etc.).
Edge Cases:
- No specific edge cases to consider for this basic implementation beyond ensuring the counter increments correctly.
Examples
Example 1:
-
Initial State (Component Loaded):
- Component's
countproperty:0 - Template displays:
Count: 0 - Button is visible and clickable.
- Component's
-
After clicking the button once:
- Component's
countproperty:1 - Template displays:
Count: 1
- Component's
Example 2:
- After clicking the button five times consecutively:
- Component's
countproperty:5 - Template displays:
Count: 5
- Component's
Constraints
- The solution must be implemented in TypeScript within an Angular project.
- You should create a single component.
- The component should be standalone or part of a module.
Notes
- Recall how to declare a property in your Angular component class.
- Think about how to display a component's property value in its template.
- Consider Angular's syntax for binding to DOM events.
- You'll need to define a method in your component class to handle the button click event.
