new syntax?
 

can anyone explain to me why the syntax was changed in the following?

$1 &lt; $2 instead of $1 < $2
$1 &lt;= $2 instead of $1 <= $2
$1 &amp;&amp; $2 instead of $1 && $2

how come only these ones changed and yet some of the others stayed the same?

i dont think it changed i think those are more on the side of html just showing the < as &lt; on the browser.

ah ok, really confused me when i saw that
