How to remove first element of a array in JavaScript
In this tutorial, we are going to learn about how to remove the first element of an array in JavaScript.
Consider we have an array with 3 elements like this.
const fruits = ["apple", "banana", "grapes"];
Now, we need to remove the first element apple
from the above array.
Removing the first element
To remove the first element of an array, we can use the built-in shift()
method in JavaScript.
Here is an example:
const fruits = ["apple", "banana", "grapes"];
fruits.shift();
console.log(fruits); // ["banana", "grapes"]
Note: The
shift()
method also returns the removed element.
Similarly, we can also remove the first element of an array by using the splice() method with 0, 1
as an arguments.
const fruits = ["apple", "banana", "grapes"];
fruits.splice(0,1);
console.log(fruits); // ["banana", "grapes"]
0 is the start index, 1 is the how many elements we need to remove from the start index.
