for your question at 07:15 we need to run npm install to clean up code as you removed alpinejs from package.json so running npm install again will remove already installed alpine package from project
sir can we say youtube or faceload is kind of running on Inertia
I honestly don't know what they are running on.
YouTube is not using Inertia or Laravel/php
YouTube's backend is primarily written in Python. It is used for tasks such as video transcoding, video processing, and video analysis. C++: C++ (And Rust from the 2022 upgrade) is used for low-level systems, such as the YouTube video player, and for performance-critical tasks such as video transcoding. Lots of part of those.
