<p>What are performance implications (if any) on parse and run-time when using function expression vs declaration in Javascript? </p>

<p>For example, what are performance characteristics and differences of the following two ways:</p>

<pre><code>var functionOne = function() {
    // Some code
}
</code></pre>

<p>or:</p>

<pre><code>function functionTwo() {
    // Some code
}
</code></pre>

<p>NOTE: The question is not about whether it is faster to declare function but about function execution. </p>
