In a nutshell: jspm combines package management with module loading infrastructure and transpilers to provide a magical experience. You can write code using today’s JavaScript, or tomorrow’s JavaScript (ES6), and use any type of module system you like (ES6, AMD, or CommonJS). jspm figures everything out. By integrating package management with a smart script loader, jspm means less work for us.
