String templates allow us to pass in arbitrary code that will evaluate to a string or an object that has a toString function. This allows us, yet again, to write cleaner code instead of having to create a bunch of concatenated strings. It also allows us to write multiline strings without having to create escape sequences. This can be seen as follows:

const literal = `This is a string literal. It can hold multiple lines and
variables by denoting them with curly braces and prepended with the dollar 
sign like so ${}.
here is a value from before ${a}. We can also pass an arbitrary expression 
that evaluates ${a === 1 ? b : c}.
`
console.log(literal);

Just remember that even though we can do something, doing something may not be the best idea. Specifically, we may be able to pass arbitrary expressions that will evaluate to something, but we should try to keep them as clean and simple as possible to make the code more readable.
