How to find Javascript syntax errors
<p>I am writing a JavaScript section of code and am making huge amounts of silly mistakes in the syntax.  But the only way to find what line the error is on is to start commenting out the section of code I just wrote and reload it into the browser to narrow down where my missing ');' is.</p>

<p>How do you "compile" a JavaScript source to make sure it is syntactically correct so that I can debug it in the browser?</p>
