Is there a way to detect which version of javascript this engine has? on console and browsers
for example i want to know conformance of
/usr/bin/js
/usr/bin/node
/usr/bin/ringo
/usr/bin/rhino
/usr/bin/seed
/usr/bin/gjs
and browsers i currently using, etc
are they Javascript 1.8.5 compatible or not, or which version of javascript they had
Check the following similar scenario.Hope this helps

Try the following script to know the Javascript version
<script type="text/javascript">
var jsver = 1.0;
</script>
<script language="Javascript1.1">
jsver = 1.1;
</script>
<script language="Javascript1.2">
jsver = 1.2;
</script>
<script language="Javascript1.3">
jsver = 1.3;
</script>
<script language="Javascript1.4">
jsver = 1.4;
</script>
<script language="Javascript1.5">
jsver = 1.5;
</script>
<script language="Javascript1.6">
jsver = 1.6;
</script>
<script language="Javascript1.7">
jsver = 1.7;
</script>
<script language="Javascript1.8">
jsver = 1.8;
</script>
<script language="Javascript1.9">
jsver = 1.9;
</script>
<script type="text/javascript">
alert(jsver);
</script>
