Explore the evolution of graphics APIs in this JSConf talk, starting from the birth of OpenGL to modern WebGL implementations. Dive into the contrast between functional and imperative programming paradigms in graphics development. Discover how the original OpenGL API, despite its stateful nature, paved the way for powerful GLSL shaders. Learn about WebGL's capabilities and challenges, including its availability in modern browsers and mobile devices. Examine the impact of functional and reactive programming on WebGL, transforming it into a more accessible and powerful tool. Investigate the stack-gl manifesto and its core modules, as well as gl-react and gl-react-native for declarative effects. Explore UI widgets and components that surpass HTML5 Canvas capabilities, all while leveraging Rx.js streams for efficient management.
