title: What does a string literal mean in Coffeescript
body: <p>The <a href="http://coffeescript.org/#strings" rel="nofollow">Coffeescript docs</a> contain the following blurb</p>
  
  <blockquote>
    <p>String Interpolation, Block Strings, and Block Comments
    Ruby-style string interpolation is included in CoffeeScript. Double-quoted strings allow for interpolated values, using #{ ... }, and single-quoted strings are literal.</p>
  </blockquote>
  
  <p>Can someone explain what <em>"single-quoted strings are literal"</em> means here?</p>
  
  <p>Does it just mean that there will be no interpretation?  Is there a more <em>javascripty</em> meaning?</p>
  
  <p>I ask because I was seeing a difference when using a single quoted string vs a double quoted as a object key.</p>
