How come you can keep redeclaring variables with const?

Once you declare a variable with const I thought it meant that it became fixed globally. In the video, I am not sure if everytime you declare ' const driver = new selenium.Builder().forBrowser("chrome").build(); ' to open a driver you are exiting the REPL, then re-entering before you declare the variables again? If I don't do that I get a SyntaxError, which I would expect. Am I missing something or should I just use a different variable name if I'm not exiting the REPL?

I don't know if its clear I'm referring to the WebDriver videos

You should probably post a question like this in the category of the appropriate language (you can move it using "edit question").

But assuming it's JavaScript (or something with similar syntax) you can re-do a "const" declaration in a function or a loop because any previous variable has gone out of scope and been disposed before you create the new one.

Thanks, it was specifically about a video, it wasn't in a function or a loop, just in command line. Don't worry about it, I'll just chalk it up to the mysteries of this place, along with why I can't put the question on the page of the video.

You could also post a link to the video page, with a time index of where you saw the issue.
