Like most other languages, I only learned the swear words.

That depends -- which job am I applying for, and how many questions are you going to ask about what's on my resume?

EDIT: I suppose if I'm going to bother posting, I should also actually answer the question. I use mainly Python and C, though I've learned and used several others to a greater or lesser degree over the years. Also, I quite like sed if we're doing scripting languages.

In order of learning:

• Basic
• Fortran
• Pascal
• 6502 Assembler
• Cobol
• C
• Unix shell
• Quel
• Awk
• Troff
• Perl (my favorite)
• SQL
• C++
• Java
• PL/SQL
• Javascript

Surprised no one else here knows HTML

Edit: I'm also good with XML

Proficient: Rust, C++, Python, x86-64 ASM, SSE1 SIMD, C#, C, Javascript / Node.JS
Can get by: Java / JNI, Kotlin, Bash
Been a while: Perl, Haskell, Prolog, Labview, Lisp

I guess I’ll be the representation of knowing none

I find this question very interesting. What does it mean to "know" a programming language. They map to certain paradigms for how to solve problems, in various degrees, with different tradeoffs there for surrounding tooling, libs, and what not.

A bunch of the most familiar ones are procedural with different sprinkles on top, and they pretty much do the same things when it comes to the "language" side. So, "knowing" one, or another, IMO, has little to do with the syntax, parsing and keywords, and is much more if you have suffered through cryptic compile errors, figured out good debugging tooling, etc.

Which is to say, if we compare these two list

• C++, Haskell, Prolog
• C++, Java, Python, Rust, Kotlin, Objective-C, Dart, etc

I'd consider the first one much more impressive in terms of diversity in "knowing programming languages". And, I say that as someone belonging squarely in the latter.

A little of them all, just enough to be a jill of all trades but a mistress of none.

Yaml & Json.

In rough chronological order: Basic, Pascal, 6800 asm, 68000 asm, C, Smalltalk, Python, Java, Javascript. Worked with but wouldn't claim to "know": Fortran, COBOL, Prolog, Lisp, C++, Rust, Go.

proficient at some point in the last 20 years:

• C
• ladder logic (for PLCs - dont take this from me)
• Verilog
• VHDL
• C#
• C++
• PHP
• Go (this is my daily driver)

I would hate to count JavaScript and friends.

Well?

• JavaScript (and TypeScript)
• PHP
• Bash (is that a programming language?)

Poorly?

• Java

Including markup and querying languages?

• HTML
• SQL

Including languages that definitely aren’t programming languages?

• Regex
• CSS

No actual programming language, but I do know a few scripting languages...

Bash, Powershell and PHP, all with various proficiencies.

Enough that I can code in pretty much anything. I think the typing point was when I coded professionally in my 4th or 5th language some time in the early 90s.

I'm not great at any language but I know mainly Python, PowerShell, and some Bash. I don't like Bash.

The first Programming course I took was in C++ which I actually like the syntax of. Unfortunately I have not used it in years. The course was also pretty simple with exclusively simple CLI programs so I never had to worry about anything like garbage collection or optimization. So the only c++ programs I have written are quite similar to something similar in Python or PowerShell.

The second course was in C# but I don't really remember anything except that classes exist.

It's not a programming language but I also know HTML and CSS.

I really should learn JavaScript someday. Rust also seems to be pretty good.

Perl is supposedly pretty good too, so I should learn that for scripting.

Depends on your definition of "know". Honestly nowadays I don't feel too scared to try something in any language.

I'm most proficient in Java and Python. In my free time I nowadays spend most of my time messing around with Haskell, Julia, or Rust. And I have some basic knowledge in a lot of other languages, including C, C++, C#, Kotlin, Groovy, Prolog, JavaScript, SQL, etc, etc.

But as I said in the beginning, I'm not too scared of learning something new. If someone were to ask me for a job where I'd be using Go or Kotlin or something then I'd be fairly confident that I could adjust quite quickly.

C, Lua, Lisp.

I can do enough HTML to customize my MySpace profile

English

I know Python, R, the STATA ado-language (a horrible proprietary progamming language), MATLABs language, Javascript and some minimal C++. What I know really well though is R and Python. So typical profile for a (data) scientist.

Roughly C, C++, Python, Java... But not all of them on an expert level.

• CL
• RPG II
• RPG III
• RPG400
• RPGILE
• PL/SQL
• SEQUEL
• SQL
• Assembler
• This line intentionally blank
• Basic
• Visual Basic

C, C#, C++, BASIC, and Java.

I see others mentioning PHP and HTML but when I learned those way the hell back in high school, most nerds would get up your ass for calling them "programming languages." If those count, I know those too.

Would VBS (Virtual Battle Simulator) scripting be a programming language? I know that best from the 3,000+ hours spent making missions for Arma 2 and 3.

I took a programming class in highschool, so I know some BASIC. Not that I've ever used it since then.

Know:

• Python
• Matlab
• Halcon
• VPM
• basic
• C/C++
• C#
• JavaScript/Typescript
• SQL

Want to learn:

• Rust
• Go
• Kotlin

I've dabbled in a LOT more, but if I had to give an honest answer to languages I could write whatever I want with it the answer is probably C, C++, Python, JavaScript, Java, C#, Bash.

I've been meaning to learn Rust, and all of the people here claiming it's their favorite language is very interesting, but I haven't found the time because it's just not relevant to what I do for work (and not likely to change anytime soon).

Programming languages in which i have done some project besides basic exercises: Python C# C++ Java

The most used and known is Pyrhon

Professionally, I’ve worked with Python, C++, C# and Java. Also briefly a little bit of Perl.

Outside work, I’ve also done JavaScript, Go and Haskell.

There are many more languages I’ve played around with, but I don’t want to list them all.

In high school I took classes on Visual Basic, C++, and Java, and learned some ActionScript on my own, but I wouldn’t feel confident with any of them nowadays. I suppose I could still write a basic HTML 4 page, but CSS was always a weak point and I don’t think either of those really count as programming languages anyways.

Enough of some to get me into trouble. I edited nethack to give me 95% probability to get wands of death, but then everyone got wands of death. And I still know Hypercard.
