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\"<

Answer 1

Simply use:

var util = require('util');

var value = 15;
var s = util.format("The variable value is: %s", value)
