server:

I have 2 select list about sbu list and department list. I want to update department list according to onChange event selected value of sbu list item. but as per my codes it sometimes workd only when I change a value it updates not with currently selected value but works that value which selected value is lost.

I was following a tutorial on YouTube of freecodecamp with the title “MERN Stack Tutorial – Book Store Project”
I am trying to run it on port 5555
I am still at the start of project just trying to check if the server is running or not
