Increasing understanding of the JavaScript length property
<p>I have the following JavaScript code. I have initialised an array using the new keyword, and therefore creating a new instance of the array object. I then populate the array by adding elements to it.</p>

<p>However I think I have made a fundamental misunderstanding - it is the next part of the code that has massively confused me, please correct my terminology if it is not clear enough or it is just plain wrong. I have logged     <code>(beatles.length)</code>. I am using the length property to find out how many elements are in the array. But why is it that length is a property and not a method? </p>

<p>Is it not the case that length is actually a method that the Array object can invoke that returns a numeric value? If length is not a method then why is it a property (a variable belonging to the array object)? Please explain the distinction here in a succinct way.</p>

<pre><code>var beatles = new Array();
beatles[0] = "John";
beatles[1] = "Paul";
beatles[2] = "George";
beatles[3] = "Ringo";

console.log(beatles.length);
</code></pre>
