We can cover all situations by creating a function that takes two arguments: array and index that you can set anew every time you have a different combination of fruits. Let's imagine that we can have different fruits, or different number of fruits, or our savoury fruit may be at a different position. concat() without any explicit loops, or unshift() or push() with. Of course, when startindex is zero or startindex - 1, the efficiency of this solution is poor, compare to just using. While the splice() method deletes the value with its associated index to maintain the. For this, we need to exclude the avocado fruit by slicing the array twice, taking the parts before and after it. reverse() the newvalues array, instead of incrementing insertindex for each iteration. It does not change the arrays length even after deleting an element. For instance, we can create a new array with only sweet fruits inside it. You can create functions that apply more than one method to the data. Let's look how we can write a more advanced code with slice.
