Objects, arrays, and transactions
مبتدئ~30 د0/4 خطوات
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.
