What is the technique in JavaScript to eliminate a particular element from an array?

edit

The technique to eliminate a particular element from an array in JavaScript is to use the Array.splice() method.

The syntax for using Array.splice() method is:

array.splice(start_index, number_of_elements_to_remove);

Here, startindex is the index position of the element to start removing from, and numberofelementstoremove is the number of elements to remove starting from the startindex.

For example, to remove the element "apple" from the array ["banana", "apple", "orange", "grapes"], we can use the array.splice() method like this:

let fruits = ["banana", "apple", "orange", "grapes"];
fruits.splice(1, 1);

console.log(fruits); // Output: ["banana", "orange", "grapes"]

In the above example, we pass the startindex as 1 (which is the index position of "apple" in the array) and numberofelementsto_remove as 1 (since we want to remove only one element). This removes the "apple" element from the array.
