<p>Get the boolean value at <code>index</code> without modifying or coercing
|
|
the value. Returns 1 if the value is <code>true</code>, 0 if the value is
|
|
<code>false</code>, not a boolean, or the index is invalid.</p>
|
|
|
|
<p>Note that the value is not coerced, so a "truthy" Ecmascript value
|
|
(like a non-empty string) will be treated as false. If you want to coerce
|
|
the value, use <code><a href="#duk_to_boolean">duk_to_boolean()</a></code>.</p>

=fixme
|
|
An API primitive which coerces but doesn't modify value? This would be
|
|
closest to ordinary Ecmascript use. The current behavior comes from the
|
|
idea that duk_get_xxx() calls do not coerce anything.
