Logic - Calculate quantity of fruit with coverage of possible test cases

logic.js

/*
  Write a function that takes input of arrays and loops over them to calculate return values based on some criteria. For example, take this array  [['oranges', 1], ['apples', 2], ['grapes', 7]]. Based on this array return total costs if second array property is a quantity and product is first array item. If say Oranges cost $5, and user buys the quantity of 2 or more, apply a 20% discount etc.. Return total cost from array by adding them all up.
  
  Let's assume:
  Orange = $2
  Apple = $3
  Grapes = $5
