I picked 11 languages that I found to be interesting:

C, C++, Python, JavaScript, Java, Ruby, Scala, Rust, Kotlin, TypeScript, Swift.

Then for each language I created categories (7 in total):

- Job Results from Indeed Japan

- Release Year

- Salary in Yen

- Stack Overflow's Dreaded Languages

- Stack Overflow's Loved Languages

- Stack Overflow's Wanted Languages

- Tiobe Rank

After that, I first discarded 63 % of the suboptimal languages from each category (37 % rule). And selected (roughly) 37 % of the most optimal languages from each category.

Finally, I gave a point for the top 37 % languages in each category, and it culminated to:

1. Python

2. JavaScript

3. Rust & TypeScript

4. C

IOW: the 37 % rule tells me that these programming languages are decent.

Python, JavaScript/TypeScript and C have a solidified job market already. (More than 9000 results; ignoring the outlier TS. A minimum salary of 800000 yen.) The only outlier with the lowest result was Rust. (Kotlin was the second lowest, and Swift the 3rd lowest.) But the heavy Stack Overflow weighing (42 %) brought Rust into the top 4.

So the answer is: Rust. (The language that I would like to use in a professional setting, but can't.)

I think the spirit of the question is "what if you didn't have to check other people's opinion and the job market to pick a language?", it's kind of the opposite of what you've done here.

Well not quite. I based it on the Stack Overflow developer surveys as well (Tiobe too). Tiobe is basically a measure for how often a language is searched for, if I am not mistaking. Rust for example has a small market share (based on the Indeed Japan results). I still want to use Rust (even if I don't get to use it in a professional setting).

Though, I understand your sentiment, but I guess it's a "technically I am right situation". Or what do you think?

Tl;dr: I picked Rust. :)

Edit: Though on a second thought: you are actually right! :) Sorry OP!
