Problem 1: Image Not Displaying Properly

Solution

Explanation:

Relative Path: The path to the image must be correct relative to where the component is rendered. In this case, moving up to the src level and then into img ensures that React can locate your image file correctly.

Problem 2: Dynamic Button Functionality

Another common challenge arises when implementing dynamic behavior for buttons in your React application. In this instance, the need is for buttons that filter tasks based on their completion status, without removing them from the view. In essence, when a task is marked as completed, a button should visually reflect that state.

Solution

To create dynamic buttons in your todo app, you will need to modify the render method of your Main component. You can use the React state to determine which tasks are completed and dynamically render buttons accordingly.

Here’s an example of how to implement this:

Explanation:

Conditionally Rendering: This line checks if a specific task (for instance, at index x) is marked as completed. If true, it renders a button labeled "Complete". This approach allows you to keep the tasks visible while enabling a functional interface for users.

Manage State: By maintaining the application’s state in React, you can easily control which buttons are displayed based on user interactions with the todo items.
