+#### ArrayValues
+
+return all the values of map as a slice of values with corresponding type
+
+```go
+res = pgo.ArrayValues(map[string]int{"a": 1, "b": 2, "c": 3}) // []int{1, 2, 3}
+
+res = pgo.ArrayValues(map[int]float64{1: 123.33, 2: 22, 3: 123.33}) // []float64{22, 123.33, 123.33}
+```

 #### Range
 
 creates an int slice of min to max range
