What I learned

I learned to create a calculator algorithm from scratch in vainilla JavaScript and then implement it in React by utilizing hooks. I also learned how to position elements in CSS with the grid-row and grid-column properties.

After this, I will be either finishing the Todo app challenge from Frontend Mentor, or doing their Country REST API one.
