The original fruits array is modified, but the original elements are preserved in the new pFruits array. In this example, we use splice() to create a new array called pFruits, which contains only the element at index 3 (Pineapple). create a new array with only the fruits that start with 'P' If you want to keep the original array intact, you should create a new array with the desired elements using splice(), as shown in the example below: let fruits = This can be useful when you want to remove elements from an array and then perform additional operations on the resulting array. This means you can use it to remove elements from an array without creating a new one.
Keep in mind that splice() modifies the original array. As a result, the second and third elements (Banana and Orange) are removed from the array. In this example, we begin removing elements at index 1, and remove a total of 2 elements. remove the second and third elements (Banana and Orange)Ĭonsole.log(fruits) // The splice() method takes two arguments: the index at which to begin removing elements, and the number of elements to remove.įor example: let fruits = shift() - removing the first element from an array.pop() - removing the last element from an array.delete - remove an element from an array without preserving the original array.indexOf() - find the index of a specific element in an array.filter() - create a new array that only contains elements that meet certain criteria.splice() - remove elements from a specific index in an array.
