So, this is apparently how you concatenate a list of Strings or should I say cities 😉 (with a delimiter between each element but excluding the last one)

I wish my esteemed colleague at least had decency to hide the fact he copied it from SO 😭

Question: what's wrong with this code❓

Who is a programmer?

One question to the devRant gods: why make rants uneditable after five minutes?

I find no reason to this. Even the paid version does not eliminate this restriction.

All social media I know allow editing your posts afterwards (with some, showi g a change history).

Maybe... are the rants stored in a blockchain❓ 😱😂😂

❓Question:

I've recently been introduced to reactive programming, and I'm wondering some things about it

- How new of a concept is it?
- Can it be declared as a third type of programming compared to OOP & FOP?
- How common is it?
