Template literals

Template literals are a nice functionality because we can create strings without the need to concatenate the values.

For example, consider the following examples written with ES5:

const book = { 
  name: 'Learning JavaScript DataStructures and Algorithms' 
}; 
console.log('You are reading ' + book.name + '.,\n and this is a new line\n   and so is this.'); 

We can improve the syntax of the previous console.log output with the following code:

console.log(`You are reading ${book.name}., 
   and this is a new line 
   and so is this.`); 

Template literals are enclosed by backticks (`). To interpolate a variable value, we will simply set the variable value inside a dollar sign and curly braces (${}), as we did with book.name.

Template literals can also be used for multiline strings. There is no need to use \n anymore. Simply hit Enter on the keyboard to take the string to a new line, as was done with and this is a new line in the previous example.

This functionality will be very useful in our examples to simplify the output!
