# Using array predicates An array predicate allows you to filter items by their position in the current context. This predicate is used after a location step, in square brackets, to return one or more items based on their index. The table below describes the syntax to use. | Syntax | Description | Examples | | --- | --- | --- | | [index] | Returns the item with the specified index. |

.customer[0] returns the first item in the customer array.
.customer[-1] returns the last item in the customer array.

| | [index:] | Returns items whose index is equal to or greater than the specified
index. |

.customer[-3:] returns the last three items in the customer array.
.customer[2:] returns all items in the customer array starting from the third one.

| | [:index] | Returns items whose index is equal to or lesser than the specified index.

Information noteNote: When used with a negative number, this syntax subtracts the specified
value from the size of the array and compares the result to the indexes in the array.
For example, for an array with 5 items, [:-2] returns all items whose
index is lesser than or equal to 5-2, so it returns indexes 0 to 3
and only ignores the last item, which has the index 4. |

.customer[:5] returns the first six items in the customer array.
.customer[:-2] returns all items in the customer array except for the last one.

| | [start\_index:end\_index] | Returns items between the first index and the second index. Both the start index
and the end indexes are included in the result. |

.customer[2:5] returns the third, fourth, fifth and sixth items in the customer array.
.customer[-3:-2] returns the third and second items from the end of the customer array.
