How to remove element from an array in JavaScript?

arrays, javascript

Solution

For a more flexible solution, use the `splice()` function. It allows you to remove any item in an Array based on Index Value:

var indexToRemove = 0;
var numberToRemove = 1;

arr.splice(indexToRemove, numberToRemove);

Problem

``` var arr = [1,2,3,5,6]; ``` Remove the first element I want to remove the first element of the array so that it becomes: ``` var arr = [2,3,5,6]; ``` Remove the second element To extend this question, what if I want to remove the second element of the array so that it becomes: ``` var arr = [1,3,5,6]; ```
