Why do we need to Use Console.log( ) in Code editor in javascript?

We need to use Console.log( ) in code Editor because we don't have Console in code editor (e.g Visual studio code, Brackets) instead we need to use "<script> </script> "to write console.log( )  in the editor to output the message in web console.. So basically this is like building a bridge between a script to develop our console that lives in the Browser.
