JavaScript is one of the most important scripting languages on the web. Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote. Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes.Starting Price: Free -

Preact provides the thinnest possible Virtual DOM abstraction on top of the DOM. It builds on stable platform features, registers real event handlers and plays nicely with other libraries. Most UI frameworks are large enough to be the majority of an app's JavaScript size. Preact is different: it's small enough that your code is the largest part of your application. That means less JavaScript to download, parse and execute - leaving more time for your code, so you can build an experience you define without fighting to keep a framework under control. Preact is fast, and not just because of its size. It's one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation. We automatically batch updates and tune Preact to the extreme when it comes to performance. We work closely with browser engineers to get the maximum performance possible out of Preact.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 -

Nova
Panic
If we're being honest, Mac apps are a bit of a lost art. There are great reasons to make cross-platform apps — to start, they're cross-platform — but it's just not who we are. Founded as a Mac software company in 1997, our joy at Panic comes from building things that feel truly, well, Mac-like. Long ago, we created Coda, an all-in-one Mac web editor that broke new ground. But when we started work on Nova, we looked at where the web was today, and where we needed to be. It was time for a fresh start. It all starts with our first-class text-editor. It's new, hyper-fast, and flexible, with all the features you want: smart autocomplete, multiple cursors, a Minimap, editor overscroll, tag pairs and brackets, and way, way more. For the curious, Nova has built-in support for CoffeeScript, CSS, Diff, ERB, Haml, HTML, INI, JavaScript, JSON, JSX, Less, Lua, Markdown, Perl, PHP, Python, Ruby, Sass, SCSS, Smarty, SQL, TSX, TypeScript, XML, and YAML.
