Making Videos with Manim

Manim could be used to make videos for non-mathematical purposes as well. In this post, I will try to use Manim to replicate a video from ByteByteGo. Here is the video:

When I try to replicate this video, I want to decompose the video into many reusable parts. For instance, the introduction part should be same for all the videos. The goal is to write resuable code so that I can make many videos with less effort.
