The languages that pay best are the ones fewest people use

Median compensation by programming language used

Go sits at a median of ₩100–120M and Bash at ₩80–90M, while JavaScript, TypeScript and HTML/CSS all land at ₩50–60M. Python, SQL and Java sit in between at ₩60–70M. Rows share respondents: almost everyone here uses several languages, so this ranks the people who use a language, not the language itself.

Every answer is one step, so a position is a rank on the scale rather than a point on a linear axis.

Language tracks the job, not the paycheque: Go and Bash cluster around backend and infrastructure work at foreign employers, where the pay gap already showed up. Go rests on ten pay answers and its middle half spans ₩70–80M to ₩120–140M, so read the ordering rather than the gaps. Languages with fewer than ten pay answers, Kotlin and Rust among them, are not shown.

10 groups with fewer than 10 answers are not shown (93 respondents).

Groups differ in more than the split shown, so read these as descriptions, not causes.

Job hunters write Python, the employed write TypeScript

Languages used, by whether people are working

76% of students and job-seekers use Python against 59% of people currently working, while TypeScript runs the other way: 40% against 54%. That fits what each group spends its days on, coursework and machine-learning portfolios on one side, product and web work on the other.

Use Python

Use TypeScript

Each gap is around 15 points with margins near ±12, so this is a lean, not a rule.
