<h1 id="logging">Logging</h1>

|
|
<p>Duktape has a built-in logging framework with a small footprint, reasonable
|
|
performance, and redirectable output.</p>
|
|
|
|
<p>Basic usage example:</p>
|
|
<pre class="ecmascript-code">
|
|
var val1 = 'foo';
|
|
var val2 = 123;
|
|
var val3 = new Date(123456789e3);
|
|
|
|
var logger = new Duktape.Logger(); // or new Duktape.Logger('logger name')
|
|
logger.info('three values:', val1, val2, val3);
|
|
</pre>
|
|
|
|
<p>The example would print something like the following to <code>stdout</code>:</p>
|
|
<pre>
|
|
2014-10-17T19:26:42.141Z INF test.js: three values: foo 123 1973-11-29 23:33:09.000+02:00
|

</pre>
