O’Reilly Velocity Conference – New York

My favorite front-end conference has always been O'Reilly's Velocity Conference because the conference series has focused on one of the most undervalued parts of client side coding: speed. So often we're so excited that our JavaScript works that we forget that speed, efficiency, and performance are just as important.
