These days most browser libraries are developed in a node.js environment and the output of these source files are generated by tools (module bundlers) like browserify, rollup and webpack (in this particular case I think gulp-umd + gulp-concat and other gulp plugins). cloudflare CDN is distributing the output of these source files (generated using gulp). Because browsers don't implement all APIs of Nodejs, we cannot directly use these source files, but need to use a module bundler like webpack (we have two module bundlers in debian now - webpack and rollup). I have been replacing many of the build scripts to use webpack instead of rollup for some time (as rollup was accepted only a week back). Many times, there is also an extra step of transpiling before we can bundle the modules. A transpiler like babel or buble (both now available in main), convert code written in ES6 version of javascript to ES5 that browsers understand. In this particular case, we don't have the transpile step and we directly bundle the modules using gulp-umd and gulp-concat.
