title: Functions are values, meaning?
body: <p>I read this sentence, as trying to understand better anonymous functions.</p>
  <blockquote>
  <p>Because functions are values, you can pass a function as an argument into another function.</p>
  </blockquote>
  <p>I can't grasp the &quot;<em>functions are values</em>&quot; idea.<br />
  If I had to define precisely what functions are, I would say functions <em>return</em> values, or <em>functions are blocks of code</em>. Or <em>function name is a value</em>.<br />
  What does it mean &quot;functions are values&quot;?</p>
  <p>Thanks</p>
