Code cells are the basic unit of a notebook interactive coding experience.
In addition to providing a code editor, code cells show the output and results of executing the code.
The top of a code cell has a small toolbar of cell-related functions: a button to run the cell, a drop-down for switching languages, buttons for hiding the code or output and a button to copy output to the clipboard (if present).
Polynote provides a modern code editing experience (interactive autocomplete, error highlighting) built with the Monaco Editor.
The last expression in a cell is treated as its result (just as a Scala function returns the result of the last
expression). This result is saved as the
Out variable and is displayed in the cell's result section.
Polynote just shows the value and simple type of simple results. For more complex results, Polynote shows a data view that allows more inspection of the data.
Nested data can be explored directly in a tree-like view.
