LINDEX key index
Available since
Time complexity
O(N) where N is the number of elements to traverse to get to the element at index. This makes asking for the first or the last element of the list O(1).
ACL categories
@read, @list, @slow

Returns the element at index index in the list stored at key. The index is zero-based, so 0 means the first element, 1 the second element and so on. Negative indices can be used to designate elements starting at the tail of the list. Here, -1 means the last element, -2 means the penultimate and so forth.

When the value at key is not a list, an error is returned.

LPUSH mylist "World"

LINDEX mylist -1
LINDEX mylist 3
