Clarification about console.log

I would just like to clarify the purpose of adding in "console.log("add task.."). Thanks.

console.log is used to output messages to the developer console, it doesn't do anything beyond that.

The purpose for using it in the code provided in this video is simply so that you can see that clicking on a button is actually triggering the function, since you at this point don't have any code in there that makes any kind of visible change occur. Without the console.log message you would not get any indication that the code was actually running at all.
