Algorithms or OO stuff or new technology

Question

I am trying to learn new stuff about jquery, html, asp .net mvc. I see two school of thoughts -

1. Those who use oo concepts a lot and stress on more object oriented approach
2. Those who rely heavily on algorithms and say a particular problem should take o(n) etc.

I am not sure where to spend more time ? . Should I spend more time learning OO stuff or learn new stuff like jquery etc or learn travelling sales man algorithm etc ?

Answer 1

Number 1 is software engineering, aka secrets of the trade. Number 2 is computer science, aka theory. Both are important, but it's much easier to pick up the former on the job. If you have time to exclusively dedicate to study (rather than read a blog post or an article here and there), I'd go with algorithms over libraries and practices any day.
