Please check out the tutorial on JavaScript Arrays to learn more about arrays. The splice () method is used to add or remove elements of an existing array and the return value will be the removed items from the array. deleteCount) is omitted, all elements from the start to the end of the array are removed, as you can see in the above example. The slice () method of Array instances returns a shallow copy of a portion of an array into a new array object selected from start to end ( end not included) where start and end represent the index of items in that array. ![]() ![]() It is important to note that the splice() method modifies the original array on which it is called on, and returns a new array of the deleted elements, or an empty array if no elements were deleted.Īlso, if the second argument (i.e. Removed = fruits.splice(2) // Removes all elements starting at index 2Ĭonsole.log(fruits) // Prints: Ĭonsole.log(removed.length) // Prints: 3 Removed = persons.splice(2,2) // Removes the third and fourth elementsĬonsole.log(persons) // Prints: Ĭonsole.log(removed) // Prints: Ĭonsole.log(removed.length) // Prints: 2 These changes alone should accomplish your stated goal. Var removed = colors.splice(2,1) // Removes the third elementĬonsole.log(colors) // Prints: Ĭonsole.log(removed) // Prints: (one item array)Ĭonsole.log(removed.length) // Prints: 1 Your index also needs to be ansx + x, because each splice() is increasing the length of the array by 1.
