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

I guess I’ll be the representation of knowing none

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 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

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.

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

Bash, Powershell and PHP, all with various proficiencies.

C, Lua, Lisp.
