ESC 6 variable and string part 3

Template Literals in ES6

Template literals are a way to output variables in the string. 
Prior to ES6 we had to break the string, for example:

let name = 'David';
let msg = 'Welcome ' + name + '!';
console.log(msg);Try It Yourself

ES6 introduces a new way of outputting variable values in strings. The same code above can be rewritten as:

let name = 'David';
let msg = `Welcome ${name}!`;
console.log(msg);Try It Yourself

Notice, that template literals are enclosed by the backtick (` `) character instead of double or single quotes.
The ${expression} is a placeholder, and can include any expression, which will get evaluated and inserted into the template literal.

For example:

let a = 8;
let b = 34;
let msg = `The sum is ${a+b}`;
console.log(msg);Try It Yourself

To escape a backtick in a template literal, put a backslash \ before the backtick.
