JavaScript code coverage compliments your existing JavaScript tests by adding code coverage statistics (which lines of your source code are covered by your tests). Parsing the code using Esprima and node-falafel, and instrumenting the file by adding code tracking lines. Connecting to hooks in the test runner to output the coverage details after the tests have been completed. A Grunt plugin has been created to allow you to use Blanket like a "traditional" code coverage tool (creating instrumented copies of physical files, as opposed to live-instrumenting). Runs the QUnit-based Blanket report headlessly using PhantomJS. Results are displayed on the console, and the task will cause Grunt to fail if any of your configured coverage thresholds are not met.Starting Price: Free -

CoffeeScript
CoffeeScript
Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to node.green for full details. You can run the tests in your browser to see what your browser supports.Starting Price: Free -

Prerender
Prerender
Get higher rankings by serving crawlers a static HTML version of your Javascript website, without compromising your customers’ experience. Prerender® is a SaaS platform that makes your JavaScript website SEO-friendly. Before your customer can find your website on search engines like Google, it first has to be crawled and indexed by one of their web crawlers, such as Googlebot. They do this by reading and cataloging a stripped-down, HTML version of your website with the visual and interactive elements taken away. This normally isn’t an issue if your website is built in static HTML, and typically takes just a few days. If your website is made in a JavaScript framework, it’s a different story. While Google can crawl websites built in JavaScript, it’s much harder for them to do. It can easily take weeks before your JavaScript website can be indexed and found in the search results. Google will see all of your content and links, and get your website in front of your customers in no-time.Starting Price: $90 per month -

The HTML source is formatted and highlighted to make it easy to read. When "Tap To Inspect" mode is active, tapping any element on the page inspects that element. This means you don't have to search through the source to inspect the element you want, it's just a tap away! Inspect allows you to view (and edit!) an element's CSS rules. Any applicable CSS rules are displayed, as well as any rules that are inherited from parent elements. Rules are ordered in order of precedence to help you debug CSS conflicts. Test your responsive design using Inspect's built-in device preview tools.Starting Price: $7.99 -

Playwright
Playwright
Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Test on Windows, Linux, and macOS, locally or on CI, headless or headed. Playwright waits for elements to be actionable prior to performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts - the primary cause of flaky tests. Playwright assertions are created specifically for the dynamic web. Checks are automatically retried until the necessary conditions are met. Configure test retry strategy, capture execution trace, videos, screenshots to eliminate flakes. Browsers run web content belonging to different origins in different processes. Playwright is aligned with the modern browsers architecture and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.Starting Price: Free -

Modernizr
Modernizr
Modernizr tells you what HTML, CSS, and JavaScript feature the user’s browser has to offer. It’s a collection of superfast tests, or “detects” as we like to call them, which run as your web page loads, then you can use the results to tailor the experience to the user. All web developers come up against differences between browsers and devices. That’s largely due to different feature sets, the latest versions of the popular browsers can do some awesome things which older browsers can’t, but we still have to support the older ones. Modernizr makes it easy to deliver tiered experiences and make use of the latest and greatest features in browsers that support them, without leaving less fortunate users high and dry. Modernizr is a small piece of JavaScript code that automatically detects the availability of next-generation web technologies in your user's browsers. Modernizr uses feature detection to allow you to easily tailor your user's experience.Starting Price: Free -

TypeScript
TypeScript
TypeScript adds additional syntax to JavaScript to support a tighter integration with your editor. Catch errors early in your editor. TypeScript code converts to JavaScript, which runs anywhere JavaScript runs: In a browser, on Node.js or Deno and in your apps. TypeScript understands JavaScript and uses type inference to give you great tooling without additional code. TypeScript was used by 78% of the 2020 State of JS respondents, with 93% saying they would use it again. The most common kinds of errors that programmers write can be described as type errors: a certain kind of value was used where a different kind of value was expected. This could be due to simple typos, a failure to understand the API surface of a library, incorrect assumptions about runtime behavior, or other errors.Starting Price: Free -
