| var arrNum [5]int // this is an array | |
| var sliceNum []int // this is a slice | |
| fmt.Println(arrNum) // [5]int{0,0,0,0,0} array have initial value of zero value | |
| fmt.Println(sliceNum) // []int(nil) slice have initial value of nil value | |
| sliceNum == nil // true | |
| arrNum[0] = 1 // ok | |
| sliceNum[0] = 1 // compile time error because you cannot assign values to nil | |
| var arrNum2 [3]int | |
| arrNum = arrNum2 // compile time error because length is part of array type | |
| sliceNum := []int{0,0} | |
| sliceNum2 := []int{1,2,3} | |
| sliceNum = sliceNum2 // ok, you can assign slice of diffrent length to a slice | |
