String Interpolation

Stuck on this task!

First, declare a constant named name and assign to it a String containing your name.

let name = "Ruby"

Second, declare a constant named greeting. Set the value of greeting to an interpolated string that combines "Hi there, " with the string stored in the name constant. As an example, the final value of greeting could be "Hi there, Linda".

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

This does not seem to work! What am I doing wrong??

for task 1 you only need 2 constants. they need to be called name and greeting. so your first line is fine. your greeting is almost there, just add the name and slash like you have at the end of your third line (and delete the third line) and it will pass.

Hi Ruby!

Well, you got the syntax right for the string interpolation so that's great! -- In your greeting constant you have to interpolate your name, basically hardcode "Hi there, " and interpolate your name.

"is the process of evaluating a string literal containing one or more placeholders, yielding a result in which the placeholders are replaced with their corresponding values."

for example:

let name = "Ruby"
let interpolation = "Proceed to the next challenge \(name)!"

Hope this helps! ?
