Code Wars

Small enough to embed anywhere, which is why it ended up scripting games, mod systems and network gear.

Built around matrices, with a paid license and a toolbox for every field. Universities and engineering teams run on it.

Windows scripting that passes objects between commands instead of plain text, so output keeps its structure.

Made by statisticians for statistics. Indexing starts at one instead of zero, which trips up everyone arriving from another language.

You snap colored blocks together and they cannot fit in a way that breaks. It is how a lot of people meet programming at school.

Glue for the command line: pipe one program into the next. Quoting is where the bodies are buried.

A whole language for slicing text line by line, and it fits in a command. Still the fastest way to get a column out of a file.

Statistics software with its own language, entrenched in pharmaceutical trials and banks where regulators expect it.

You describe the result you want and the database works out how to get it. Every vendor then adds its own dialect on top.
