Code Wars

Built for web pages and still runs a large share of them. You can drop it in the middle of HTML, which is both the point and the complaint.

Built at Google for large teams: few features on purpose, one formatting style, and compiles fast enough to feel scripted.

Drag a window together, double-click a button, write what happens. It made Windows apps buildable by people who were not programmers.

Tracks who owns each piece of memory at compile time, so whole classes of crashes stop being possible. The compiler argues back.

JavaScript with a type checker bolted on top. The types vanish when it compiles, so nothing survives to runtime to catch you.

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.

Reads almost like English and enforces layout with indentation, so the spacing is not a style choice — it is the syntax.

Basic's scripting cousin, wired into Windows and Internet Explorer. It also became a favorite delivery method for email viruses.
