Today I Learned

1. Concatenating Domains with Paths:

   • Domain: Avoid trailing slashes (e.g., "example.com" over "example.com/").
   • Path: Start with a slash (e.g., "/api/endpoint" over "api/endpoint" or "//api/endpoint").

2. Removing Trailing Slashes:

   • JavaScript Function:

   function removeTrailingSlash(str) {
     return str.endsWith('/') ? str.slice(0, -1) : str;
   }
   

Following these practices ensures proper URL formatting, avoids issues, and promotes clean and standardized URLs.
