-  Implement a function `calculateTotalSpentByCategory` which takes a list of transactions as parameter
-  and return a list of objects where each object is unique category-wise and has total price spent as its value.
-  Transaction - an object like { itemName, category, price, timestamp }.
-  Output - [{ category1 - total_amount_spent_on_category1 }, { category2 - total_amount_spent_on_category2 }]
 
-  Once you've implemented the logic, test your code by running
-  - `npm run test-expenditure-analysis`
