title: How can I see the source of built-in JavaScript functions?
body: <p>E.g., alert(), Object(), String(), etc. How would I see the code behind these functions?</p>
  <p>Would I need to understand the language that an engine, such as <a href="https://en.wikipedia.org/wiki/V8_%28JavaScript_engine%29" rel="nofollow noreferrer">V8</a>, is written in and read through that, or is there a simpler solution?</p>
