This script, part of the PostHog platform, is responsible for enabling and managing in-app surveys. It loads survey definitions configured in the PostHog dashboard and displays them to target users based on predefined conditions (e.g., page views, user properties, events). It handles the presentation of survey questions (multiple choice, open text, etc.), collects user responses, and submits them back to the PostHog analytics platform. The script ensures surveys are displayed at appropriate times and manages state to prevent repeat displays or to save partial progress. It operates client-side, interacting with the DOM to render survey widgets and capturing user input. Data collected is sent to PostHog's backend for analysis and reporting.
