I think "in 2020" is more fun. No, I'm kidding. I will update the title next week to not limit it in "2020" only. Thanks for your comment
Leave it. It helps with the SEO and, if anything, it will show first for beginners when they search for it. It's an important article and the 2020 really doesn't hurt anyone
So, I'll let the title as it is.
I don't think these methods were really necessary in 2019, but now? Can't do without them.
haha that is brilliant response.
I'd say they were necessary in 2018 and possibly even earlier. All these "in 2020" articles are clickbait in my opinion.
This is your opinion, and I fully respect it. However, I've added "in 2020", to just make this article easy to find for beginners. And also knowing these methods is relevant for 2020, in my opinion, because most of them introduce you to functional programming.
