STRING CONCATENATION:
let greeting = "Hi there, " + name // heavily uses the plus sign => " + "
STRING INTERPOLATION: let greeting = "Hi there, (name)" // Uses " ONE SET OF DOUBLE QUOTATION!", No need for the plus sign, "+" // but uses a special syntax ==> () <== // store the given properties either let or var between the parenthesis => (name)

So you would do something like this
let name = "Paul Karim" let greeting = "Hi there, (name)."
In front of (name) you need a backslash :) but that's it.

186 PointsThank you for your help. I tried entering the code the way you typed it with the back slash but it still didn't work.
