Given an array containing some array elements and the task is to remove the first element from the array and thus reduce the size by 1. We are going to perform shift() method operation without actually using it with the help of JavaScript.
There are two approaches that are discussed below:
- Using splice() Method
- Using filter() Method
Method 1: Using splice() Method
We can use the splice() method that is used to get the part of the array.
Example: In this example, we will implement the above approach.
Javascript
let Arr = ['Geeks', 'GFG', 'Geek', 'GeeksForGeeks'];console.log("Array: [" + Arr + "]");function myGFG() { Arr.splice(0, 1); console.log("Elements of Array: [" + Arr + "]");}myGFG(); |
Output
Array: [Geeks,GFG,Geek,GeeksForGeeks] Elements of Array: [GFG,Geek,GeeksForGeeks]
Method 2: Using filter() Method
We can use the filter() method to filter out the element at index 0.
Example: In this example, we will implement the above approach.
Javascript
let Arr = ['Geeks', 'GFG', 'Geek', 'GeeksForGeeks'];console.log("Array: [" + Arr + "]");function removeFirst(element, index) { return index > 0;}function myGFG() { Arr = Arr.filter(removeFirst); console.log("Elements of array = [" + Arr + "]");}myGFG(); |
Output
Array: [Geeks,GFG,Geek,GeeksForGeeks] Elements of array = [GFG,Geek,GeeksForGeeks]
