Last thought
I hope you have a good mood when looking at these examples . Of course I am . Welcome to let me know which one you like best . Or if you have some shameful photos to share , Don't be afraid to share it in comments .
I enjoyed browsing through these code snippets . It reminds me of my early days . In my career , I wrote some code snippets that I'm not proud of . But fortunately , No one took a screenshot of them . Or at least I hope so .
