Explore web application development using Google's Polymer library in this 48-minute conference talk from Devoxx. Learn how Web Components extend HTML vocabulary with custom, reusable elements, enabling developers to build on existing work. Follow along as Radu Enuca constructs a small application from scratch, demonstrating the power of Polymer's pre-built elements and testing the claim "There is an element for that!" Discover how this approach, likened to building with Lego, can revolutionize web development by promoting code reuse and efficiency.
