Nightwatchjs vs Wallaby.js: What are the differences?

Developers describe Nightwatchjs as "Automated testing and continous integration framework based on node.js and selenium webdriver". Nightwatch.js is an easy to use Node.js based End-to-End (E2E) testing solution for browser based apps and websites. It uses the powerful Selenium WebDriver API to perform commands and assertions on DOM elements. On the other hand, Wallaby.js is detailed as "Intelligent test runner for JavaScript with real-time code coverage and deep editor integration". It is an intelligent test runner for JavaScript that continuously runs your tests. It reports code coverage and other results directly to your code editor immediately as you change your code. Wallaby.js uses various tricks to run your tests as fast as possible, such as dependency analysis to only execute tests affected by your code changes and parallel test execution. It provides a huge productivity boost whether you are doing TDD/BDD or using any other approach.
