how long to learn one programming language ?

Udemy courses or codeacadamy would be a good place to start I guess. What programming language are you trying to get into?

0.5 years for a noob
2 years for a pro
all over 3 years is masterclass

but it also depends on which

The trick is to look at the big picture and then fill in the details later. Know what you're trying to accomplish in broad strokes. The language is moot, having a familiarity with what libraries are available is handy though (for example, machine learning in python, or serving web content via node.js). Even full time developers like me just stackoverflow for specific syntax and tactics all day long, the main thing is getting familar with strategies, patterns, and overall design.

well dont be like me and start on java its so hard

I don't really know.
It just took me some time of watching Youtube videos, stackoverflow, etc.
I learned as I went

you can learn the basics in a few weeks if you really want

I reccomend learning the OG "C", it can be a great link to any other languages if you get the basics down pat

yeah probably but anyway who cares bro like what does it change anyways its all a scam

Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you Thanks you

Basically i learned LUA by 3 years , and that was amazing experience , i think this is one of the best languages, its real "flexable" (can be used for big amount of things)
