scope of variables within a function

I'm confused about one of the questions following the video: 'Using constants with array and objects'. I understand the intent of the CONST variable but I thought variables declared within a function have a local scope, and it was a best practice to not reuse variable names to avoid confusion. I thought it was explained in a previous course that it was possible to reuse a variable name within a function because of the limited scope, but not a good practice. Does that not apply to CONST when its been declared globally?
