The function returns a new array containing the copied values.The multidimensional array: profile =, ,, ,, ,, ] Ī map function for iterating over the array and returning only the matched results. If end is greater than the sequence length, slice extracts through to the end of the sequence.For example, slice(1,-1) extracts the first element through the second-to-last element in the sequence. If negative, it extracts until the end of the sequence.If not supplied, it extracts to the end of the sequence.end (optional) : The ending index of the copied array.If start is greater than the index range of the sequence, an empty array is returned.

If negative, it indicates an offset from the end of the sequence.If not supplied, it starts from index 0.

start (optional): The starting index of the copied array. slice doesnt mutate the array on which it operates so you need to assign a value to what it returns let list 1,2,3,4,5 const removeElement list.indexOf (3) // remove number 3 var newList list.slice (0, removeElement).concat (list.

This example slices out a part of an array starting from array element 1 ('Orange'): Example const fruits 'Banana', 'Orange', 'Lemon', 'Apple', 'Mango' const citrus fruits.slice(1) Try it Yourself Note The slice () method creates a new array.
