And as a matter of fact, in ES6, backtick strings have a special use case that we're going to look at now, and that's when we need to insert data into strings. Prior to ES6, whenever we wanted to insert the values of variables into strings, we had to either use the plus sign or the built-in string .concat method to do so. And both of these serve their purposes well-enough, but in practice, they can be a little cumbersome to use.
