Fetch-script

Fetch script is a toy language built on top of Javascript, specifically designed to fetch API resources.
The primary goal of the language to be succinct yet powerful.
The front-end app aims to bring an experience close to python notebooks: on the left are the code sections, that can be executed independently from each other. Results "echoed" from the scripts are shown under each section, while all variables are always accessible in the right-side column.

$options.apis.sample.baseURL = "http://jsonplaceholder.typicode.com"

users = /sample/users
all = /sample/users/{users[*].id}
  [posts] = /sample/posts/?userId={@.id}
  [first_post_title] = @.posts[0].title
