...SystemJS allows to write and use modular javacsript code that relies on ECMAScript 6 import and export statements. One good example is moment.js library, which started publishing ECMAScript 6 source code on npm since 2.10.0 release of moment.js. SystemJS requries a transpiler to compile ECMAScript 6 javacsript into a code that could be run in current versions of browsers and node.js.
