Answer 1

Just use this code:

var foo='"bar"';
alert(foo);

Answer 2

When you use 'x', x can't be ' character (I mean the basic usage) and the same thing, if you have "x", x can't be ".

Soulutions:

1- Using single-quote inside double-quote:

  console.log("'x'");

2- You can also print a character by its Unicode, ' Unicode is \u0027

   console.log('\u0027\u0027'.toString());

3- escape apostrophes by \

 console.log('I\'m JavaScript console.log');

Answer 3

You need to escape " and alert:

Example snippet:

var foo = 'bar';
alert("\"" + foo + "\"");

Answer 4

Basically you can do this

    var foo='"bar"';
    alert(foo);
