Objects, arrays, and transactions
Move from single values to a ledger
An object groups the fields that belong to one transaction. An array holds many transactions. Array methods let you transform that real structure instead of copying totals by hand.
The included rows are explicitly marked as practice data. Your job is to render them and derive income, expenses, and balance from the array.
Instructions
Use filter to select income transactions.
Hint: Filter where item.type === 'income'.
Where does this go?
// Use map to render rows and reduce to calculate totals.Write it on line 8 — under that comment, after the code you already added.
