Tip Calculator App using Javascript, SCSS

What are you most proud of, and what would you do differently next time?

❤Things I've tried

• Created validation as a separate function for code refactoring

• Used Object.entries() converting object to an array for better refactoring

• Scored 99% on Google PageSpeed Insights

• Considered web accessibility

• Responsive for Mobile, Tablet, Desktop devices

💪Things I should improve

• Javascript : JavaScript is getting harder🤣 Need to practice a lot.
• Code refactoring :The first code I wrote was too long and repeated. I need to study more about how to write code efficiently.

Please let me know if there are any areas of improvement! Thanks :D
