Booleans |
default |
true
and false
are used for true and false, respectively. However, any value may be converted to a boolean using the $istrue
function, which returns false for false
, null
, and 0
, and true for anything else. The $not
function does just the opposite. For if
and while
expressions, only true
will be considered true.
&&
is logical "and" and ||
is logical "or". These operations are short-circuited and do not convert the values to booleans.
For example:
{% highlight javascript %} $print(false || "Hello"); //prints "Hello" {% endhighlight %}
