Help with concatenation.

Need help better understanding concatenation, pretty sure I am not doing this one right!

strings.swift 
// Enter your code below

let name = "TJ"

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

let finalGreeting = greeting + name + How are you?

Hey, you've basically got it. When you're concatenating strings with the addition operator you can add constants or variables to strings of text, but new strings of text need quotes around them. So "How are you?" should have quotes around it. Another tricky part is remembering to put spaces between words when concatenating them with the addition operator. You can do this by adding a space in quotes (as shown below). In this example you also want to add some punctuation.

Also, the constant "greeting" already has the constant "name" in it because of the string interpolation. So if you were to print "finalGreeting" it would read "Hi there, TJTJHow are you?". So we can go ahead and leave "name" out of the "finalGreeting".

// Enter your code below

let name = "TJ"

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

let finalGreeting = greeting + ". " + "How are you?"

alternatively you could write

// Enter your code below

let name = "TJ"

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

let finalGreeting = greeting + ". How are you?"
