Modernizr vs. RequireJS vs. Three.js vs. jQuery Comparison Chart

Modernizr tells you what HTML, CSS, and JavaScript feature the user’s browser has to offer. It’s a collection of superfast tests, or “detects” as we like to call them, which run as your web page loads, then you can use the results to tailor the experience to the user. All web developers come up against differences between browsers and devices. That’s largely due to different feature sets, the latest versions of the popular browsers can do some awesome things which older browsers can’t, but we still have to support the older ones. Modernizr makes it easy to deliver tiered experiences and make use of the latest and greatest features in browsers that support them, without leaving less fortunate users high and dry. Modernizr is a small piece of JavaScript code that automatically detects the availability of next-generation web technologies in your user's browsers. Modernizr uses feature detection to allow you to easily tailor your user's experience.

Three.js is a JavaScript 3D library. The aim of the project is to create an easy-to-use, lightweight, cross-browser, general-purpose 3D library. The current builds only include a WebGL renderer but WebGPU (experimental), SVG and CSS3D renderers are also available in the examples. To actually be able to display anything with three.js, we need three things, scene, camera, and renderer, so that we can render the scene with the camera. In addition to the WebGLRenderer, Three.js comes with a few others, often used as fallbacks for users with older browsers or for those who don't have WebGL support for some reason. Create a loop that causes the renderer to draw the scene every time the screen is refreshed (on a typical screen this means 60 times per second). Anything you want to move or change while the app is running has to go through the animate loop. You can of course call other functions from there.
