Cosa significa il dollaro in questo codice di esempio?

function Person(first_name, last_name) {
     this.first_name = first_name;
     this.last_name = last_name;

     this.displayName = function() {
         console.log(`Name: ${this.first_name} ${this.last_name}`);
     };
}

Non mi pare che c'entri con jquery.
