How to interpolate variables in strings in JavaScript, without concatenation?

Question

I know in PHP we can do something like this:

$hello = \"foo\";
$my_string = \"I pity the $hello\";

Output: \"I pity the foo\"<

Prior to Firefox 34 / Chrome 41 / Safari 9 / Microsoft Edge, no. Although you could try sprintf for JavaScript to get halfway there:

var hello = "foo";
var my_string = sprintf("I pity the %s", hello);
