AVA Tutorial

avajs/ava : 🚀 Testing can be a drag. AVA helps you get it done.

A concurrent test runner from the Andromeda galaxy. If I was to stray from Jasmine then it could only be for a project Sindre Sorhus is working on :) The screenshots on the project site promised extensive assertion failure output with clean stack traces and built-in Promise, async/await, Observable and React component support. So I tried it out and yup, AVA delivered.

Get Started

# Install
npm init ava

# Run tests
npx ava --watch --verbose

.NET Regex Tutorial

Not nearly as confusing as it is in JavaScript.

using System.Text.RegularExpressions;

Match match = Regex.Match("input", @"\w+");
IReadOnlyList<Match> matches = Regex.Matches("input", @"\w+");
string result = Regex.Replace("input", @"(\w+)", "$1");

Moment.js Tutorial

Moment.js is a legacy project, now in maintenance mode. In most cases, you should choose a different library.
See some alternatives at the end of this post.

Proceed at your own peril

Moment.js is a mutable wrapper with a fluent interface for the native JavaScript date object (property _d). Use .toDate() to convert back to a JavaScript date.
