Note content sinks are obsolete! You can now directly interpolate CL variables into a note. Interpolation supports string, number, and latex types. For example, you can define the following variables on your note component:
myVariable = when c1.number("a") > 0 "positive" otherwise "negative or 0"
anotherVariable = c2.content
number = 0
latex = `\sin x`
Then, you can select myVariable
, anotherVariable
, number
, or latex
after pressing the { # } button or typing ${ into the note’s text area. You can mix interpolated variables with regular text and even style them. The values of these variables will be displayed to your students.
