JavaScript - Delete First Occurence of Given Element from a JS Array

These are the following ways to delete elements from a specified Index of JavaScript arrays:

1. Using indexOf() and splice() - Most Used

The indexOf() method finds the first occurrence of the element in the array, and splice() removes it at that index. This approach directly modifies the original array.

[ 1, 2, 4, 3, 5 ]

2. Using filter() method

The filter() method is used to create a new array that excludes the first occurrence of the element, without modifying the original array.

[ 1, 2, 4, 3, 5 ]

3. Using findIndex() with splice()

The findIndex() method returns the first occurrence of the element matching the condition, if it exists the splice() method is used to remove the element.

[ 1, 2, 4, 3, 5 ]

4. Using for loop

The for loop manually iterates over the elements of the array to find and delete the first occurrence. The loop is stopped immediately after deleting the element.
