For this task, I'd probably use string interpolation (e.g. $ and {} around arguments. That would produce cleaner code.

"Hello [name], today's date is [current date]. You have [count] new notifications."
Use variables for: name is "John", date is today's date, and notification count is 3.
Format the date as mm/dd/yyyy.
Show the output.
