Welcome to Visual Array

Using the buttons you can visualise how the basic array instance methods work. The array will be displayed and updated as you add or remove items.

To Add Items

push

.push inserts an umbrella emoji at the end of the array

unshift

.unshift inserts a lightning bolt emoji at the beggining of the array

insert at

Insert at uses the .splice method to insert a snowman emoji at the chosen index (use the dropdown selector)

Remove Items

pop

.pop removes from the end of the array

shift

.shift removes from the beginning of the array

remove at

Remove at uses the .splice to remove from the chosen index (use the dropdown selector)
