Challenge on interpolation! This code won't run in the editor. It says error but I can't seem to see where I went wrong.
let name = "Machok" let greeting = "Hi there" let interpolatedGreeting = "(greeting), (name)."

let name = "Machok"
let greeting = "Hi there, \(name)."
let finalGreeting = greeting + " How are you?"
What they are showing you here with the greeting string is that you can interpolate a value (the name value in this case) inline using a backslash and surrounding the value name with brackets. Take note of the comma and space before the value to ensure it spaces right, and the full stop after the value to get the punctuation correct.
The second step with the finalGreeting is showing you that you can concatenate strings together too. You can see we have the greeting value (from the previous step) followed by a string literal. Take note of the space at the start of the string literal. This is because a space would not be added in concatenation and you need to take care to add them yourself where needed.
