Refining and Improving the Trading Journal

Feature Additions

I've been adding features that make the application more complete:

• Edit and delete trades
• Form validation
• Better error handling
• Improved UI feedback

These might seem like small things, but they make a huge difference in how the app feels to use.

Form Validation

I learned about form validation in React. It's important to validate user input before it's saved. I'm checking for required fields, valid numbers, and reasonable date ranges.

Code Organization

I've been refactoring my code to be more organized. I created separate files for utility functions, types, and constants. The codebase is getting larger, and organization matters.

What I've Learned

This project has taught me:

• How to structure a larger React application
• State management with Context API
• Form handling and validation
• Data persistence with local storage
• Basic analytics and calculations

I've come a long way from my first todo app.

Challenges

The hardest part has been keeping everything organized as the project grows. I'm learning that good code structure is just as important as working code.

Almost There

I'm getting close to having a complete application. There are still some features I want to add, but the core functionality is there. I'm excited to finish this and move on to the next project.
