JS Template strings (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...):

Template strings are enclosed by the back-tick, `string text ${expression} string text`

  var a = 5;
  var b = 10;
  console.log(`Fifteen is ${a + b} and not ${2 * a + b}.`);
  // "Fifteen is 15 and not 20."

You can also 'tag' a template string:

  tag`Hello ${ a + b } world ${ a * b}`;

where the 'tag' is a preprocessor function.

For you, yes. I work in an organisation with over 100000 non savvy users and I've not seen a single person that has successfully switched default search engine from Bing to Google in IE. They just complain about search "being bad".

For the former, there's this tiny little library that I use for everything:
