how long to learn one programming language ?

it really depends from every person but idk it's average 3 months but it can take lower depends on your effort you put in andpractice

It depends, if you follow tutorials this might take not that long, months maybe, if you want to learn by yourself, it will take you way longer, but if you're good at reverse engineering, you'll get a good understanding of code

I would give myself 3/4 of a year or a full year. To master it I'd give myself 2 years and then it'll get easier after the 1st language is learned.

I quite honestly can't offer a lot of advice, as I only work in HTML and CSS. But, I can say that the world of code is ever expanding, there are even things being constantly added to the latter mentioned programming languages. As such, I wouldn't really define a specific time to learn a specific language, as there's always something more you can learn.

your best bet will be to use udemy prbob its easy and not hard to use

oui je joue au COD parce que c'est bon jouer et trs drle des jeux vido

depends on your skills and interest. the more you want it the easier it gets. it took me 3 years to be very good now

epends on programming language.
For example: Python syntax can be learned in 5 days, and master paradigms - even for a lifetime

python took me 3 weeks to learn fully and C took me around 2 months

You have to get the idea of how programming works, languages aren't hard to learn, since only the syntax changes.
