RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including eventhub-xxl. Try it out:
const EventHub = require('eventhub-xxl').EventHub;
const eh = new EventHub();
function myFuncA(state) {console.log('FuncA: ' + state)}
function myFuncB(state) {console.log('FuncB: ' + state)}
function myFuncC(state) {console.log('FuncC: ' + state)}
eh.on('foo', myFuncA, {phase: EventHub.PHASES.BUBBLING});
eh.on('foo.bar', myFuncB, {phase: EventHub.PHASES.CAPTURING});
eh.on('foo.bar.baz', myFuncC);
eh.trigger('foo.bar.baz', 'ok');
