I have found out that you can use jQuery with node.js but all examples are for DOM and HTML manipulation.
Do you think using it for array iterations ( for each ) etc would be ok or a bit overkill?
Most of the common jQuery utilities are already in implemented in the V8 engine, which node.js is built on.
for example, compare:
One of the best things about node.js is that most of the ES5 spec is already there.
Underscore.js is a much smaller utility library for manipulating objects.

npm install underscore
EDIT:
However, node.js has much better support for ES5 than browsers, and it's likely that you may not even need a library for manipulating objects. See keeganwatkins' answer.
NodeJS already has all the EcmaScript 5 Array Extras builtin. For example if you want all the odd squares:
[1,2,3,4,5,6,7,8,9].map(function(n){
return n*n;
}).filter(function(n){
return n%2;
});
//-> [1, 9, 25, 49, 81]
If you would like to see the other methods on the arrays, you can go to my JavaScript Array Cheat Sheet .
If you want the sum of all the cubes, you can:
[1,2,3,4,5,6,7,8,9].map(function(n){
return n * n * n;
}).reduce(function(p, n){
return p + n;
});

jQuery has some nifty non-DOM features you can borrow -

Just strip out what you do not need (like a reference to window).
If there are just a few functions you want to add, an alternative to adding a full library is to just implement the functions you want:
Many functions that are partially supported on some browsers are documented in MDN with compatibility code that can be used to add the function: Array.forEach
