Answer 1

Stevie, your second &quot;shorter&quot; way is actually 3 characters longer and is harder to understand for beginners. Nice try though.

Answer 2

The long way:

var value = document.getElementById(&#039;number&#039;);

if (value &lt; 1000 || value &gt; 1999) {

alert(&quot;The value wasn&#039;t between 1000 and 1999.&quot;);

}

The short way:

var value = document.getElementById(&#039;number&#039;);

(value &lt; 1000 || value &gt; 1999) ? alert (&quot;The value wasn&#039;t between 1000 and 1999.&quot;) : &#039;&#039;;

Answer 3

var value = document.getElementById( &#039;number&#039; ).value;

if ( value &lt; 1000 || value &gt; 1999 ) {

alert( &#039;The number was not between 1000 and 1999.&#039; );

}
