This code helps us to remove data from the array.

Splice.js

//First, find the index of the element you want to remove:

var array = [2, 5, 9];
var index = array.indexOf(5);

//Then remove it with splice:

if (index > -1) {
    array.splice(index, 1);
}

//The second parameter of splice is the number of elements to remove. Note, splice modifies the array in place and returns a new //array containing the elements that have been removed.
