The Arrays are the most commonly used data structures in JavaScript, allowing developers to store and manipulate collections of items.

Syntax

array(index, deleteCount[, element1[, element2[, ...]]])

Parameters

Here, we have three parameters to remove a particular element from an array in JavaScript ?

• index ? The index at which to start changing the array.
• deleteCount ? The number of elements to remove.
• element1, ..., elementN(optional) ? The elements to add to the array.

Return Value

It returns an array that removes a particular element from the original array.

Removing a particular element from an array in JavaScript

Removing a particular element from an array in JavaScript is quite easy. Let's learn through the following programs ?

• splice() Method
• filter() Method
• slice() Method

Using Splice() Method

The splice() Method is used to remove one or more elements from an array.

Example

let array = [1, 2, 3, 4, 5];
let array = [1, 2, 3, 4, 5];
let index = 2; 
if (index > -1) {
  array.splice(index, 1);
}
console.log(array);

Output

The above program produce the following result ?

[ 1, 2, 4, 5 ]

Using filter() Method

This filter() method is used to filter out the elements based on a condition.

Example

let array = [1, 2, 3, 4, 5];
let valueToRemove = 3;
let filteredArray = array.filter(item => item !== valueToRemove);
console.log(filteredArray);

Output

Following is the output of the above program ?

[ 1, 2, 4, 5 ]

Using slice() Method

Here, the slice() method is used to extract a portion of an array without modifying the original array.

Example

let array = [1, 2, 3, 4, 5];
let valueToRemove = 3;
let index = array.indexOf(valueToRemove);
let newArray = array.slice(0, index).concat(array.slice(index + 1));
console.log(newArray);

Output

Following is the output of the above program ?

[ 1, 2, 4, 5 ]
