When using CoderPad to write code in the browser, say your on the go and just need to write some code, and that code happens to be JavaScript and you want to run a Mocha test here is what you need to do:
'use strict';
const { expect } = require('chai');
const Mocha = require('mocha');
const mocha = new Mocha({ui: 'bdd'});

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
I was trying to solve an issue with starting the ExpressJS server before each single test and closing it after each test completes, just to make sure each test is running under the same conditions.
Here is the error I ran into while trying to run the tests
$ ./node_modules/jasmine/bin/jasmine.js

We dropped Lerna from our monorepo architecture in PouchDB 6.0.0. I got a question about this from @reconbot, so I thought I'd explain our reasoning.
First off, I don't want this post to be read as "Lerna sucks, don't use Lerna." We started out using Lerna, but eventually outgrew it because we wrote our own custom thing. Lerna is still a great idea if you're getting started with monorepos (monorepi?).
Backstory:
Should be work with 0.18
Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !
myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))
