Example question component that is only shown after a previous question is answered correctly. I haven't tested this but it should provide the basic structure.

How to use:
[var name:"q1Correct" value:false /]
[Question options:`["test1", "test2"]` trueAnswer:"test1" correct:q1Correct /]
[var name:"q2Correct" value:false /]
[Question options:`["test1", "test2"]` trueAnswer:"test2" correct:q2Correct showAfter:q1Correct /]

Loading data with Parcel
View GUIDE.md

This is a quick guide to loading static files with Parcel. There are two ways to load data in JavaScript:

  • including the data in the JavaScript bundle itself
  • fetching the data as an external resource

Including data directly in the JavaScript bundle

This is the preferred way of doing things if your data payload is relatively small (<1 MB) as it will lead to fewer network requests (which often gives better perfromance).

Setting value on a variable just defines its initial value, if you want a variable that updates derived variables are available:

[var name:"x" value:1 /]
[derived name:"dataToBeCharted" value:`[ {x: 0, y: 0.5}, {x: 3.5, y: 0.5}, {x: 4, y: x}, {x: 4.5, y: 2}, {x: 5, y: 0.5}, {x: 8, y: 0.5} ]` /]

[Range value:x min:0 max:100 step:5/]
[Display value:x /]
