 ### Square The Data
 
-Pass an array of integers you want to sqaure it
+Use mapObject to return a object from array passed as an argument which gets sqaured as math operation
-Here using `.reduce()` the new object is accumulator and one by one values from array are passed and go through function.
 
-```
+```js
-const arr = [1,2,3,4,5,6,7];
+const squareIt = arr => mapObject(arr, a => a*a)
-arr.reduce(function(a,b){
+squareIt([1,2,3]) // { 1: 1, 2: 4, 3: 9 }
-a[b] = b * b;
-return a;
-},{}) // {1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49}
