Array Functions

array values have the following functions defined.

• add
• clear
• contains
• indexOf
• insert
• lastIndexOf
• remove
• removeAt
• length
• getEnumerator

Note: The functions that return array just return the value they acted on, not a new value. This enables calls to be chained like this: [].add(1).add(2).add(3)

lastIndexOf

lastIndexOf(item): number
