Web Development

Joining a web development community can be a challenge within itself, especially when all the resources you visit assume you're familiar with other technologies that you're not familiar with.

Our goal is to help you avoid that mess and come up to speed as fast as possible; you can consider us your internet friend.

CDN

Content Delivery Network

This is typically a paid service you can use to get great performance for your app. Many CDNs act as caching proxies to your origin server; some require you to upload your assets to them. They give you a URL for each resource in your app. This URL will resolve differently for folks depending on where they're browsing.

Behind the scenes, the CDN will distribute your content geographically with the goal of end-users being able to fetch your content with the lowest latency possible. For example, if a user is in India, they'd likely get content served from India faster than from the United States.

CoffeeScript, TypeScript

These are both languages that compile to JavaScript. You're able to write your code using the syntax they offer and when ready you compile your TypeScript or CoffeeScript into JavaScript.

LESS, Sass

Both LESS and Sass are types of CSS preprocessor markup intended to give you much more control over your CSS. During the build process, the LESS or Sass resources compile down to vanilla CSS (which can be executed in a browser).

Linter, linting

A validation tool which checks for common issues in your JavaScript. You'd usually use this in your build process to enforce quality in your codebase. A great example of something to check for: making sure you've always got your semicolons.

UI

UI stands for User Interface and is essentially what the user sees and interacts with on a device. In terms of the web, the UI is generally composed of a series of pages containing visual elements such as buttons and icons that a user can interact with to perform a specific function.

Shadow DOM

Not to be confused with Virtual DOM. Shadow DOM is still a work in progress, but basically a proposed way to have an "isolated" DOM encapsulated within your app's DOM.

Creating a re-usable "widget" or control might be a good use-case for this. Browsers implement some of their controls using their own version of a shadow DOM.

Virtual DOM

Not to be confused with Shadow DOM. The concept of a virtual DOM means abstracting your code (or in our case, Ember) away from using the browser's DOM in favor of a "virtual" DOM that can easily be accessed for read/writes or even serialized.
