How is Bower different than jspm? Can Bower provide jspm functionality about SystemJS universal module loader?
To add on to Capaj's answer:
If you have a small project, go with jspm anyway! It's the future! (who knows, things change, but this is a good bet).
Small project use:
$ jspm install jquery
then in your HTML:
then in main.js:
import $ from 'jquery'; // ES6-style import
// do whatever with jQuery here.
You can use CommonJS, AMD, or ES 6 module formats. JSPM auto-detects them in your files (you can't mix and match in the same file though).
var $ = require('jquery'); // CommonJS-style import
// do whatever with jQuery here.
define(['jquery'], function($) { // AMD-style import
// do whatever with jQuery here.
})
