Context Functionality

The context (TodoContext) in this application provides centralized state management and functions for managing todos. Here's a brief overview of its functionality:

• todos: An array of todos containing objects with id, todo, and completed properties.
• addTodo: A function to add a new todo to the list.
• updateTodo: A function to update an existing todo based on its ID.
• deleteTodo: A function to delete a todo from the list based on its ID.
• toggleComplete: A function to toggle the completion status of a todo.

Implementation of Context API

The Todo App uses the Context API to manage state and provide todo-related functions to its components. Here's how the context is implemented:

• Creation: The createContext function from React is used to create the TodoContext.
• Provider: The TodoProvider component is exported to provide the TodoContext to the component tree.
• useTodo Hook: The useTodo custom hook is created to access the TodoContext and its provided values within components.
• Value: The TodoProvider component wraps around the top-level component (App) to provide the context and its values (todos, addTodo, updateTodo, deleteTodo, toggleComplete) to all nested components.

Usage

Once the Todo App is running, you can use the following functionalities:

• Add Todo: Enter a new todo message in the input field and press the "Add" button.
• Update Todo: Click on the edit icon (✏️) next to a todo to edit its message. Press the save icon (📁) or Enter to save the changes.
• Delete Todo: Click on the delete icon (❌) next to a todo to delete it.
• Complete Todo: Click on the checkbox next to a todo to mark it as completed. The completed todos will have a strikethrough effect on their text.
