Hello Tseng,

Those back ticks indicate a template literal, where it fills in anything inside the ${ ... } with the value of the variable that is referenced inside.

You can find out more here in a video: It might be easier for you to watch that (and the next one after it too) than for me to try to explain it all.

I hope this will help explain them!

I will watch the video you suggested. And the video is really clear. Louise St. Germain Thank you !
