Visual Studio Code
There are many IDE's that can be used for front-end development. Frequently used ones are ATOM and Brackets. During this course we'll be using the light-weight, versatile and open source Visual Studio Code. VS Code isn't opinionated like many other IDE's and due to its open source nature there are many extensions available to configure it based upon your needs.

Eventually you'll need a more fine-grained selection of extensions based on the projects you're working on.
