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 middleware-resolver. Try it out:
var Resolver = require("./resolver.js");
var util = require('util');
var context = {
bla: "BLAAA"
};
var runs = 10000;
/* Job format
A jobs list is an array of job descriptors
The value for each key is a job requirements specification:
`requires` - Jobs required to be finished before this one can run.
`optional` - Jobs that, if present, should be run before this one.
`before` - Jobs that, if present, will only run after this job completes (reverse dependency)
`notif` - Don't run if task is completed. Implies optional dependency
`task` - `function (done, next)` to execute. In the function body `done("name", "aux event"); next();`
*/
var testJobs = [
{ name: "task1", task: function (done, next) { done("task1", "test"); next(); } },
{ name: "task2", requires: [ "task6" ], task: function (done, next) { done("task2"); next(); } },
{ name: "task3", requires: [ "task1", "task2" ], task: function (done, next) { done("task3"); next(); } },

- all documents on RunKit are public
require()any package directly from npm- use arrow functions, classes, template strings, and most of ES6
awaitany promise instead of using callbacks (example)- create your own embedded node.js snippets
