[survey] Front-End Code Playground tools

Hello :slight_smile: I am writing master thesis about Front-End Code Playground tools (tools for creating and testing Front-End code, operating via a web browser - e.g. CodePen, JSFiddle). I would really appreciate your taking the time to complete the following survey :slight_smile: (intended for people involved in front-end). This survey is completely anonymous, its results are intended only for scientific purposes.


Please, I still need more answers.
