    {name: "Jennie", role: "senior"},
    {name: "Ronald", role: "junior"},
    {name: "Martin", role: "senior"},
    {name: "Anneli", role: "junior"}];

Инъекции данных в строку шаблон осуществляются с помощью js-выражений, завёрнутых в сигнатуру ${expression}:

const teamName = "tooling"; 
const people = [ 
  {name: "Jennie", role: "senior"}, 
  {name: "Ronald", role: "junior"}, 
  {name: "Martin", role: "senior"}, 
  {name: "Anneli", role: "junior"} 
]; 
 
let message = `There are ${people.length} people on the ${teamName} team. Their names are ${people.map(p=>p.name).join(', ')}. ${people.filter(p=>p.role==='senior').length} of them have a senior role.”`; 
 
console.log(message);
