- [Splice vs Slice vs Split](#SDiff)

<a name=“closures”/>

The splice() method adds or removes items to or from an array, and returns the removed item(s).

NOTE: The original array will be changed by this Method.

Syntax: array.splice(start[, deleteCount[, item1[, item2[, ...]]]])

let car = ["Audi", "BMW", "Bajaj", "Aston Martin"];

car.splice(1, 0, "Chevrolet", "Chrysler");

car;

(6) ["Audi", "Chevrolet", "Chrysler", "BMW", "Bajaj", "Aston Martin"] // Added Chevrolet to car array at index of 1 and followed by Chrysler. Since Second argument is 0, none of the item is removed from an array.

let result = car.splice(1, 1); ["Chevrolet"] // Returns the removed item

car

(5) ["Audi", "Chrysler", "BMW", "Bajaj", "Aston Martin"]

The slice() method returns the selected elements in an array, as a new array object.

It selects the elements starting at the given start argument, and ends at, but does not include, the given end argument.

NOTE: The original array will not be changed. It can be used with String as well.

Syntax: arr.slice([begin[, end]])

let fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"];

let citrus = fruits.slice(1, 3);

fruits

(5) ["Banana", "Orange", "Lemon", "Apple", "Mango"]

citrus

(2) ["Orange", "Lemon"] // Doesn't included the end element- Apple in an result array.

The split() method is used to split a string into an array of substrings, and returns the new array.

Note: The split() method does not change the original string.

USE: Reverse String, Substring

Syntax: str.split([separator[, limit]])

let str = "How are you doing today?";

let res = str.split(" ");

res

(5) ["How", "are", "you", "doing", "today?"]
