Curry Entries

Instructions

This exercise consists in creating curry functions to apply in the objects entries. You will have to create the following curry functions:

• defaultCurry that will curry two objects in witch the second object must be the default object and returns a new object with the modifications applied by the first object
• mapCurry that replicate the function .map
• reduceCurry that replicate the function .reduce
• filterCurry that replicate the function .filter

You will also have to create for each curry function the following:

• reduceScore that will return the total value of the scores of the persons who use the force
• filterForce that will return the force users with shootingScores equal or higher than 80
• mapAverage that will return a new object with the propriety averageScore that is the averages of the scores for each person
