Our task is to, for each letter of the (English) alphabet, write a program that prints the alphabet, in a language whose name starts with that letter.

Input: none

Output:

abcdefghijklmnopqrstuvwxyz

uppercase and trailing newline optional

Rules:

  • The scoring metric is the length of the programming language name, plus the length of the code. Hence, C will be assessed a "penalty" of 1, while GolfScript will be assessed a penalty of 10.
  • One language/implementation per answer. Multiple answers are encouraged.
  • If a programming language name's first letter is not an English letter, it should not be coerced into one. It will be treated as a separate letter (meaning less competition).
  • No answer will be accepted until every English letter has a solution.

Current rankings:

Q is for QuadR, 8 bytes, score: 13

819⌶⎕A⋄⍵

Try it online!

Explanation

Lowercase (819⌶ - "BIg" without a boolean is un-BIg) the uppercase alphabet (⎕A). The avoids any additional output, and the means this line should be run as code, rather than as a regex transformation.


QuadR, 4 bytes, score: 9

I didn't realise it was allowed to use uppercase alphabet, which simplifies this greatly...

Prints the alphabet in uppercase. (I'm not sure whether this is allowed, but other people are doing it so...)

Just 1 character shorter than the (even more) boring answer:
