@MasterofBlockchain ./ and ../ are just the ways to tell the program about files.

./ says that look for the file in the same folder.
../ says that go back one step and look for the file in the parent folder.

one dot ./ refers to the current directory while two dots ../ refers to the parent of the current directory i.e. one directory upwards from the directory you are inside.
So for example you are in C:/users/documents/hardhat-fundme-fcc using ./<filename> will get a file inside this directory while using ../<filename> will get a file in C:/user/documents

So in your case, because 00-deploy-fund-me.js is in the deploy folder (hh-fcc/hardhat-fund-me-fcc/deploy/00-deploy-fund-me.js), while the helper-hardhat-config is one directory upwards (hh-fcc/hardhat-fund-me-fcc/helper-hardhat-config) we use ../helper-hardhat-config to access it. We use ../ to move up one directory into the parent directory then access the file.
I hope this helps you.
