You should read the article! The author goes into this in fascinating detail.
Super accessible.
That way, not only does it confirm paying attention, but you can also get a signal of course effectiveness.
For example, in JavaScript, we essentially have arrays (great for tracking order, O(n) lookup) and objects (great for O(1) lookup, no order), but that doesn't mean you can't: a) implement other data structures such as doubly linked lists, heaps, red black trees, etc. b) combine the strengths of two different data structures in a new object
I think it was Bill Gates who emphasized the importance of picking good data structures up front.
A book I recommend for learning how to implement data structures (and concomitant algorithms) is: Introduction to Algorithms (http://mitpress.mit.edu/books/introduction-algorithms)
It is also useful to have some heuristic for picking data structures, and I have found the recipe proposed by Gayle Laakmann in her book, Cracking the Coding Interview, useful in most non-esoteric cases.
A number of countries that do not have same-sex marriage do recognize foreign same-sex marriages for immigration (Israel is one example).
