3. JavaScript → Python 2 → Foo

JavaScript

Classic JS quine. This is a full program which outputs to console:

(f=_=>console.log(`print(${String.fromCharCode(39)}${String.fromCharCode(34)}(f=${f})()${String.fromCharCode(34)}${String.fromCharCode(39)})`))()

Try it online!

Python 2

Python code basically prints out the JS code with quotes:

print('"(f=_=>console.log(`print(${String.fromCharCode(39)}${String.fromCharCode(34)}(f=${f})()${String.fromCharCode(34)}${String.fromCharCode(39)})`))()"')

Foo

Foo code is JS code with quotes:

"(f=_=>console.log(`print(${String.fromCharCode(39)}${String.fromCharCode(34)}(f=${f})()${String.fromCharCode(34)}${String.fromCharCode(39)})`))()"

10. Javascript → Foo → brainfuck → Wumpus → Gol><> → RAD → ><> → Python 2 → Brain-Flak → 4

Edit: For the next answer, I've golfed how the Python generates the Brain-Flak a bit more here, but I can't be bothered to update the links.

Added Gol><>. It's just a short rpH after the Wumpus code. I've also optimised the brainfuck and Brain-Flak code somewhat. Verification!

JavaScript (Node.js)
