am i reading the question too closely based on my coding?

i need more clarity on how i should set this on up in the editor

// Enter your code below
let name = "Larry"
let greeting = "Hi there"

greeting = "\(greeting) ,+, \(,name)"

Just looking at the javascript you've posted here, seems like you're not concatenating the string correctly. You're not escaping the variables named greeting and name. You should try something like this instead.

newGreeting = greeting + " " + name;

Currently your code returns:

"(greeting) ,+, (,name)"

You can also check your code for expected output in the chrome debug console.

Matthew Bach While I can understand your confusion based on how the code looks, the code posted is not JavaScript. It is Swift, the programming language used mainly to develop apps for iOS.

When using string interpolation you don't need to use + or commas, you just type a string like you normally would and then insert the contents of variables by wrapping the variable name in \().

To get the string you are trying to produce you would just type it like this:

"\(greeting), \(name)"

However that is not the only issue with your code, greeting is a constant. A constant is a variable which cannot have it's value reassigned. Which means that you can't set it to a different value after declaring it like you do in your code.

The solution is to use string interpolation on the string you initially assign to the greeting constant, like this:

let name = "Larry"
let greeting = "Hi there, \(name)"

Yep, I totally missed the breadcrumb showing this was in the swift track! My apologies!
