### Instructions
|

|
||||
This exercise consists in creating curry functions to apply in the object's entries.
|
||||
You will have to create the following curry functions:
|
||||
You're going to create some curry functions, to apply to the object's entries.
|
||||
|
||||
- `defaultCurry` curries two objects in which the second object overrides the values of the first. If the key is not present then add it with the corresponding value.
|
||||
Create `defaultCurry`, which curries two objects. It mergers the objects together. If the key exists in both objects, the value from the second object override the value from the first object.
|
||||
|
||||
```js
|
||||
|
||||
defaultCurry({
|
||||
http: 403,
|
||||
connection: 'close',
|
||||
contentType: 'multipart/form-data',

Create `mapCurry`, which replicates function `.map` (but for an object). The first entry is the function, and the second entry is the object.

Using each curry function create the following functions with a parameter `personnel`:
|
||||
|
||||
- `reduceScore` that will return the total value of the scores
|
||||
of the persons who use the force (this function can have one additional parameter)
|
||||
- `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 average of the scores for each person
