Learn JavaScript – How To Remove a Particular Element From an Array?

When programming in JavaScript, sometimes we want to manipulate items within an Array. In this article, we show how to remove or add elements in an array using native JavaScript methods.

JavaScript – Manipulating elements at the beginning or end of an Array

Add or remove items at the beginning or end of the array is simple. The functions pop () push (), shift () and unshift () can be used for this.

The first two functions manipulate final items in the array while shift () and unshift () manipulate the initial elements. Below is an example.

The above code will result in the following sequence:


JavaScript – Manipulating intermediate items from an Array

Working with items that are in the middle of an array is not so easy, but we have the splice () function.  Its syntax is simple and requires the following parameters: the original array, the initial position, the amount of items that will be affected, and if we are adding items, their value.

The examples below show how to remove two items from the array, from the second element and the addition of a new element in the 4th position.

Important: the function makes changes directly in the original array and returns an array of items that have been affected – added or removed.
