How do I delete a specific element from an array in JavaScript

Question

Can you help me with a problem that asks how to delete a specific element from an array in JavaScript?

Answer 1

You can use the splice() method.

Code:

let arr = [1, 2, 3, 4, 5];

// Remove the element at index 2

arr.splice(2, 1);

console.log(arr); // Output: [1, 2, 4, 5]

Explanation:

splice(index, count) modifies the array in place.

index: The position where deletion begins.

count: Number of elements to delete.
