I want to know if I can remove a special element within an array using the pop() and method(). For example, let say if I want to remove shoes using the pop() method. How can I do this? I know JavaScript has remove() method which removes element from the dom.
var items = ['Hat', 'Ball', 'Shoes'];
var lastItem = items.pop();
// lastItem now holds 'Shoes'
// and items is now ['Hat', 'Ball']

var items = ['Hat', 'Ball', 'Shoes']; // your array
var index = items.indexOf('Ball'); //create a new var and use the indexOf() method and choose what you want removed
if ( index > -1 ){ // you need a conditional statement to use the splice method
items.splice(index, 1);
}
and there you go. If you have any other questions please ask. that's what we are here for.
