This is a program that runs javascript programs basically, much like "node", and takes care of the testing.

powershell -c "irm bun.sh/install.ps1|iex"

git clone https://github.com/aethne0/mengtest

You can also fork this repo first, then clone, if you want to push your code.

cd e01_ll

bun test --bail which will stop after 1 failed test, so it is easy to read, or

bun test --watch which will automatically run+output all tests every time you save ll.js
