title: Does Scala's string building form ```s"$var1"``` have a name?
body: <p>What is the name given to the way that I can create Strings in Scala like this?</p>
  
  <pre><code>val foo = "hello"
  val bar = "world"
  
  val s = s"$foo $bar"   /// &lt;-- Does this construct have a name?
  </code></pre>
  
  <p>I'm trying to find if Javascript has a similar way of building strings and I wasn't sure what to search for.</p>
