Implementing "Go to Definition" Functionality in an Angular Component

This challenge focuses on creating a simplified "Go to Definition" feature within an Angular component. The goal is to allow users to click on a component property and be directed to the definition of that property within the component's TypeScript file. This is a fundamental feature in most IDEs and enhances developer productivity by quickly navigating to code locations.

Problem Description

You are tasked with building a basic "Go to Definition" functionality for a single Angular component. The component will display a property's value and, upon clicking that value, should simulate navigating to the property's definition in the component's TypeScript file. For simplicity, this simulation will involve displaying an alert message containing the property name and a placeholder indicating the file path. The core requirement is to correctly identify the clicked property and construct the appropriate alert message.

Key Requirements:

• Component Structure: You will be provided with a basic Angular component template and TypeScript file.
• Property Display: The component should display a property named propertyName (string type) in the template.
• Click Handler: Implement a click handler on the displayed property value.
• Definition Simulation: When the property value is clicked, display an alert message. The alert message should contain the propertyName and a placeholder file path (e.g., "src/app/my-component.ts").
• No External Libraries: The solution should not rely on any external libraries beyond Angular itself.

Expected Behavior:

1. The component renders correctly, displaying the propertyName.
2. Clicking on the displayed property value triggers the click handler.
3. The click handler displays an alert message containing the propertyName and the placeholder file path.

Edge Cases to Consider:

• What happens if propertyName is empty or null? (Handle gracefully, perhaps by displaying a default message or doing nothing).
• The solution should be robust to changes in the component's template structure (e.g., adding more properties). The click handler should specifically target the property value.

Examples

Example 1:

Input: propertyName = "firstName";
Output: Alert message: "firstName - src/app/my-component.ts"
Explanation: Clicking on "firstName" triggers the alert with the property name and file path.

Example 2:

Input: propertyName = "";
Output: No alert is displayed.
Explanation: An empty property name should not trigger an alert.

Example 3:

Input: propertyName = null;
Output: No alert is displayed.
Explanation: A null property name should not trigger an alert.

Constraints

• Angular Version: Assume Angular version 14 or higher.
• TypeScript: The solution must be written in TypeScript.
• Alert Message: The alert message must be in the format "propertyName - src/app/my-component.ts".
• Performance: The solution should be efficient and not introduce any noticeable performance bottlenecks. This is a small component, so optimization is not a primary concern, but avoid unnecessary computations.
• No Navigation: This is a simulation. Do not attempt to actually navigate the user to a file in their IDE. The alert message serves as the placeholder for that functionality.

Notes

• Consider using event binding to attach the click handler to the property value in the template.
• The propertyName is a string, so you can directly use it in the alert message.
• Focus on the core logic of identifying the clicked property and constructing the alert message. Styling and other UI enhancements are not required.
• The placeholder file path "src/app/my-component.ts" is just an example; you can use any consistent placeholder.
