Interactive visualizations are a primary tool for understanding Squiggle code, but there are some additional techniques that can improve the debugging process. Here are some tips and tricks:

Basic Console Logging

  • Built-in Inspection: Utilize the inspect() function to log any variable to the console. This function provides a detailed view of the variable's current state and is useful for tracking values throughout your code.
  • Variable Settings Toggle: Click on the variable menu in the Squiggle interface and select "Log to JS Console".


Squiggle pushes its output to window.squiggleOutput. Like with the outputs of inspect, you can see this in the JS developer console (opens in a new tab).


You can call Danger.json() see variables in a format similar to JSON. This is useful for seeing all aspects of complex types like distributions.
