If it is not passed, it will delete all elements from the starting position. If it is 0, then no elements will be removed. If the value is negative the position will be counted from the end of the array.Ģnd Argument: The numbers of elements to be removed from the starting position. Splice:ġst Argument: Specifies at which position a new element or existing element should be added/removed. It will return the original array as it is at the start. See the below Example: var arr1 = Įven if you made some changes to the array it won’t affect it. Note: Slice always returns the selected elements from the array.
If you put a negative number while calling, the selection will be selected from the end of the array. If you didn’t put this in the parenthesis while calling the slice method, it will return the elements from the starting index to the end of the array. Slice:ġst Argument: Specifies from where the selection should be started.įrom the first index (5) it will return the elements.Ģnd Argument: Specifies at which level the endpoint should be. Here, I’m gonna share how I solved it with those methods.īoth Slice and Splice are used to manipulate arrays. I was confused at that time when to use Slice and when to use Splice. They already mentioned solving using Slice & Splice. I came across this freeCodeCamp challenge and got stuck for some time thinking about how I could find a way to solve it.
