CodePen provides a very easy to use interface to code and render web development projects. It is a wonderful way to code something quickly, such as proof of concepts or algorthims, which you can then save, edit, and share with your team.

How easy it makes coding! I have experience coding but when I need a leg up, CodePen is the way

CodePen is an fantastic tooling to create and share front end code to others. It suits the need to provide example or starting point of code to others as well as ask questions or ideas or improvement to the piece of code done. The tooling comes with inbuilt css, js, html and a rendering pane where you can see the output of your then and there. The tooling also highlights compiling and parsing errors. Great tooling used by our front end development team
