Budget Tracker: Your First Real Tool
Feed in a month of transactions and get back where the money actually went, which category is bleeding you, and what is left. The first tool people are proud to show.
What you'll be able to build
Feed in a month of transactions and get back where the money actually went, which category is bleeding you, and what is left. The first tool people are proud to show. Along the way you pick up real, transferable Lua skills, not just this one project:
- tables as transaction records
- accumulating totals into a category table
- for loops summing and comparing
- table.sort for ranking categories by amount
- nil-safe arithmetic with (x or 0)
- string.format for an aligned report

How the lessons actually work
Every lesson has you predict what a piece of Lua code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Budget Tracker, and a runnable proof page tied to your own code.
