Livebook is an exciting project created by Elixir to provide documentation, interactive exploration, and expose app logic in a new way. It is similar to Jupyter notebooks and was initially developed for machine learning, but it can be used on regular Phoenix web projects as well. Livebook allows developers to experiment, learn, and document the central idea of an application. It also supports code completion, code execution, and markdown text explanations. Notebooks created in Livebook are plain markdown files that can be easily added to source control. Livebook is a powerful tool that can benefit developers and enhance collaboration on projects.
