Why would you use let message for the variable on line 2 instead of just message?

I am working through the JavaScript basics course and am wondering when to use let for a variable instead of just the variable name.

Hey Melanie Gunn , when you are first declaring a variable, you need to use either var, let or const to correctly instantiate that variable. Then later, when you reference or reassign the variable, you will not use one of those keywords, but just the variable name. Hope that is helpful. :smiley:

I can't comment on the line 2 of the code you are referring to because I don't know what that is. When reaching out here, it can be helpful to share any example code and relevant links, like to the course, video or challenge you are working on and perhaps a workspace snapshot. :thumbsup:

Thank you! I figured it out. That is good to know for next time that I need to post a screenshot of my work.
