I started programming after I played some PlayStation 1 game when I was a kid. Mum told me that you have to program to be able to make games so I as a kid searched how to program and was promptly greeted by some c hello world tutorial. 9 year old kid seeing hello world in terminal did not a programmer make.
Few years later the various javascript fork-bomb stuff were riddling the internets, the ones where you had alert with some supposedly funny messages one after another (this was before stop making new dialogs was an option) which was my true introduction to programming. Doing actual real world stuff - making my friends and teachers suffer. Even if it was copy pasting alert hundreds of times, or changing the for loop end value from 10 to 100, it was very crude programming.
As long as you understand the core concepts, you can start learning more. Set a small goal and try to achieve it. Keep setting goals and try to achieve them and surely you’ll end up lerning.
Just some casual engagement farming. Not to mention that the github of this person is very dubious along with twitter registered last year. Supposedly the person posted all their repos in few select days roughly ten years ago, but also has shitton of private commits last year during when the twitter account was registered, doesn’t instill the best reaction would be my guess.
