<p>The JavaScript method toString() converts an array to a string of (comma separated) array values.</p>
<h3 id="toString"></h3>
<p>The join() method also joins all array elements into a string.</br></br>
It behaves just like toString(), but in addition you can specify the separator:</p>
<h3 id="join"></3>
<p>The pop() method removes the last element from an array:</p>
<h1 id="demo"></h1>
</body>
