Return the remaining elements of an array after chopping off n elements from the head.
The head means the beginning of the array, or the zeroth index.
TEST☟
slasher([1, 2, 3], 2) should return [3].
slasher([1, 2, 3], 0) should return [1, 2, 3].
slasher([1, 2, 3], 9) should return [].
slasher([1, 2, 3], 4) should return [].
slasher(["burgers", "fries", "shake"], 1) should return ["fries", "shake"].
slasher([1, 2, "chicken", 3, "potatoes", "cheese", 4], 5) should return ["cheese", 4].

function slasher(arr, howMany) {

}
}
slasher([1, 2, 3], 2);```
//方法1：splice()

//方法2：slice()
