How Can I Remove a Specific Item from an Array in JavaScript?

Removing Specific Array Items in Core JavaScript

Want to remove a particular value from an array effortlessly? Core JavaScript offers a straightforward approach.

Approach:

1. Utilize indexOf to determine the index of the element you wish to remove.
2. Employ the splice method to eliminate the element at that index.

splice() Method:

The splice() method allows you to modify an array by removing existing elements or inserting new ones.

Example:

Consider the array [2, 5, 9]. To remove the value 5, follow these steps:

const array = [2, 5, 9];

const index = array.indexOf(5); // Find the index of the element
if (index > -1) { // Only splice array if item is found
  array.splice(index, 1); // 2nd parameter removes only one item
}

// array = [2, 9]

In this example, the indexOf method finds the index of the value 5, which is 1. The splice method then removes the element at index 1, yielding the modified array [2, 9].
