| pop |
Removes an item from the end of a list and returns the item. In the following example, the value of a is 3, and the value of b is [1,2]. row = [1,2,3]; @.a = row.pop(); @.b = row; |
| indexOf(searchObject) |

In the following example, the value of a is [2,3], and the value of b is [1,0,0,4]. row = [1,2,3,4]; @.a = row.splice(1,2,0,0); @.b = row; |
