Hi GrowthBook team, Could you also explain when the

trackingCallback

method should be call, because it's no clear from documentation

Hello, the tracking callback should be called when experiment is run. The second argument of tracking callback is a result of the experiment

@ancient-car-96302 What does "experiment is run"? When do we simply run the experiment in the GrowthBook? or when a person reaches a place in the code where

useFeatureIsOn

is called and the experiment is launched

when a person reaches a place in the code where

feature()

is called and the experiment is launched, when #evaluateExperiment() is called tracking callback is triggered in the end of it

Thank you @ancient-car-96302!

just to clarify some of the language, the trackingCallback is called when an experiment is assigned, but you don't (well, shouldn't) call the method yourself
