Manipulate Entries

Instructions

Finish your groceries!!!

Create 3 functions that works like the .filter, .map and .reduce array method but for the entries of the grocery cart.

  • filterEntries filters using both key and value.
  • mapEntries changes either the key or the value or both.
  • reduceEntries reduce over entries.

Create 3 other functions that use your previously create functions:

  • totalCalories that will return the total calories of a cart
  • lowCarbs that will leave only items that total carbs are lower than 50grams
  • cartTotal that will give you the right amount of calories, proteins, ..., of all items in your grocery cart.
