JavaScript

Once relegated to the browser as one of the 3 core technologies of the web, JavaScript can now be found almost anywhere you find code. JavaScript developers move fast and push software development forward; they can be as opinionated as the frameworks they use, so let's keep it clean here and make it a place to learn from each other!

Client-side, server-side, it doesn't matter. This tag should be used for anything JavaScript focused. If the topic is about a JavaScript framework or library, just remember to include the framework's tag as well.

How should the tag be written? All lower-case letters for the tag: javascript.
