How can I access array element by index using MongoDB 3.0?

Question

I would like to know how I can access the elements of an array in mongo (version 3.0) by position, just as I would with $arrayElemAt in the newer versions.

UPDATED: I want to achieve the same of this example using mongodb 3.0:

Thank you very much.

Answer 1

In this case $arrayElementAt returns only one element from a given position. If you want to manipulate a chunk of items you want to return you should use $slice. Please check the link for more references: MongoDB $slice

{ $slice: 3 } //for the first 3
{ $slice: -3 } //for the last 3
{ $slice: 2, 3 } //for 3 elements after skiping the 2 frist
