Typed Explorer Step 1: Find the Bug That Types Would Have Caught
Open the Knowledge Explorer you built in the React course. Find one bug you actually hit while building it that a type system would have caught: a prop passed in the wrong shape, a field that was sometimes missing, a value that was a string where you expected a number. Write it down, including how long it took to find. Then find one bug that types would NOT have caught. Both lists matter, and the second one is what stops this course being oversold to you.
Built it in both languages?
Mark it done once your Python and JavaScript versions both run correctly. Honesty here is what makes the dashboard useful to you.
