what is the point in using the "finally" block，what is the difference from simply using a console log statement ?

@SteveGriffith-Prof3ssorSt3v3 10 ай бұрын

the finally block gives you a chance to clean up operations that were initiated inside the try or the catch blocks. It will always run and always be the last block to run in your try catch finally If something inside the try block failed, it means that you might not have a process that began. The finally is the best place to put clean up code. try{ //start trying to do something //show a loader/spinner //display some default data }catch (err){ //handle problems } finally { //hide loader/spinner... //clean up default data... } Without the finally you would have to do that clean up code inside the catch AND after the catch.
