Calculator Mortgage with react, typescript, and BEM with nested css

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

I proud on the way I handle the types and the insights I'm gaining working with them. The styles I'm applying maybe are simple but very concise and devoted to the design's photo. Also the clean code I worked through the project.

I'm pretending to work next time with css variables more in deep.

What challenges did you encounter, and how did you overcome them?

The challenge was a function and personalize their options related to the parameters of intl.NumberFormat, it was interesting because I used a utility named "ConstructorParameters" and accessing to the second parameter.

What specific areas of your project would you like help with?
