Why would someone want to use a linked-list over an array?

Coding a linked-list is, no doubt, a bit more work than using an array and one may wonder what would justify the additional effort.

I think insertion of new elements is trivial in a linked-list but it's a major chore in an array. Are there other advantages to using a linked list to store a set of data versus storing it in an array?

This question is not a duplicate of this question because the other question is asking specifically about a particular Java class while this question is concerned with the general data structures.
