Build a JavaScript Calculator Project

Can someone explain the significance of the \n in the tests?

I’m trying to figure out why tests like #8 and #9 do not work.

I initially asked another question on here, but then I found some more bugs and fixed it.

I tested the inputs of #8 and #9, and it gave the right numbers, but I do not know why they are not checked off.

Here’s my pen: https://codepen.io/CasualWanderer20XX/pen/vEYWrXp

Update: Nvm, I found some more bugs and problems with more of my code.
