Country + State + City

Hi. Its not a huge deal, but I feel its important to understand every single step. When I do the part where we say:

let address = country + ", " state + ", " + city

I get an error for some reason. Consecutive statements on a line must be seperated by ';'

What have I done wrong? I feel like I've followed our glorious professor step by step.

Thank you in advance! -Riley

You are simply missing a +, specifically it's missing before the state variable. When concatenating multiple strings and variables like that it is very easy to accidentally leave a + off. It's a pretty common error, but one that will lead to a crash.

For that reason there are a number of people who prefer to use string interpolation instead when combining many variables and strings together. As not only is it arguably cleaner and faster to type, but it makes mistakes like that easier to avoid.

Thank you so much for explaining it. That seems obvious now, but at the time I couldn't figure it out. Thanks again.
