Danke you for the clarification

We're playing the code golf (https://en.wikipedia.org/wiki/Code_golf) game, tl;dr write a solution with the minimal number of characters. Yes, in real, production code, you'd use const or let (var is still valid, but most modern code uses let unless var is absolutely necessary, since it has slightly different behavior https://stackoverflow.com/a/11444416/12101554), but this is still valid JavaScript.

Use const, let or var!!!

I changed random tests to generate squares.
Should I fork the translation for approvement?

Tests never generate squares. Code: return ($l+$w)*2; passes all tests.

Thank you. Fixed

PHP Translation

I think you should add some random tests to your translation

Thanks
