How I learn any type of new technology (as a Senior Developer)

A developer shares their process for learning PostHog, an open-source analytics platform, as an alternative to Google Analytics. The approach involves experimenting with the user interface, studying documentation, examining source code, and analyzing network requests. The author then builds a custom query builder in PHP to better understand PostHog's functionality. This hands-on method of breaking down and rebuilding components is presented as an effective way to learn new technologies and APIs thoroughly.
