In ES6 you can use template strings to more easily construct strings:
var person = { name: "Tom", age: 20 }; // Before: var string = person.name + " is " + person.name + " years old"; // Now: var string = `${person.name} is ${person.age} years old`;
Template strings also allow you to write multi-line strings:
var string = `This is<br/> a multi-line string<br/> without having to use<br/> any tricks. Pretty userful<br/> for HTML`
