Template literals provide the ability to embed expressions in string literals and support multiple lines. The syntax is to use the back-tick (`) character to enclose the string instead of single quotes or double quotes. Here is an example:

let user = {
  name: 'Ted',
  greeting () {
    console.log(`Hello, I'm ${this.name}.`);
  }
};
user.greeting();  // Hello, I'm Ted.

As you can see, inside the template literals, you can access the execution context via this by using the syntax ${...}. Here is another example with multiple lines:

let greeting = `Hello, I'm ${user.name}.
Welcome to the team!`;
console.log(greeting);  // Hello, I'm Ted.
                        // Welcome to the team!

One caveat is that all the whitespaces inside the back-tick characters are part of the output. So, if you indent the second line as follows, the output wouldn't look good:

let greeting = `Hello, I'm ${user.name}.
                Welcome to the team!`;
console.log(greeting); // Hello, I'm Ted.
                       //                Welcome to the team!
