Array.shift() Method

remove the first element of an array

Flash 5

array.shift()

Returns

The value of the first element of array, which is also deleted.

Description

The shift() method deletes the first element of an array and then moves all the remaining

elements of the array up one position. The affected array’s

length is reduced by 1. Note

that shift() differs from the pop() method, which deletes the last element of an array.

Example

myList = new Array ("a", "b", "c");

myList.shift(); // myList becomes ["b", "c"]
