The greeting() function returns a string with variables in it using string addition (sometimes called string "interpolation")
But there is another, more modern way to concatenate strings with variables in them...
Using Template Literals! 🥳
Can you refactor this function so it returns the string using a template literal?
To run the tests:
npm test template_literals.test.js
Hint: make sure you're in the correct folder before running these commands.
